Assuming that the biomass 20 of densification are completely submerged in flammable liquid 12, this flammable liquid 12 is heated to the temperature within the scope of about 160 DEG C to about 280 DEG C, or the arbitrary temp between them, the biomass 20 of densification are heated to the temperature within the scope of about 160 DEG C to about 320 DEG C, or the arbitrary temp between them, to complete roasting process.In further example, the temperature of the biomass 30 of the densification of the roasting at the end of illustrative methods can change in the scope of about 180 DEG C to about 320 DEG C, or the arbitrary temp between them, between about 180 DEG C to about 300 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 320 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 310 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 300 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 290 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 280 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 270 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 260 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 250 DEG C, or the arbitrary temp between them, between about 200 DEG C and about 240 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 300 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 290 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 280 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 270 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 260 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 250 DEG C, or the arbitrary temp between them, between about 220 DEG C and about 240 DEG C, or the arbitrary temp between them, can be maybe about 162 DEG C, 165 DEG C, 168 DEG C, 170 DEG C, 172 DEG C, 175 DEG C, 178 DEG C, 180 DEG C, 181 DEG C, 182 DEG C, 183 DEG C, 184 DEG C, 185 DEG C, 186 DEG C, 187 DEG C, 188 DEG C, 189 DEG C, 190 DEG C, 191 DEG C, 192 DEG C, 193 DEG C, 194 DEG C, 195 DEG C, 196 DEG C, 197 DEG C, 198 DEG C, 199 DEG C, 200 DEG C, 201 DEG C, 202 DEG C, 203 DEG C, 204 DEG C, 205 DEG C, 206 DEG C, 207 DEG C, 208 DEG C, 209 DEG C, 210 DEG C, 211 DEG C, 212 DEG C, 213 DEG C, 214 DEG C, 215 DEG C, 216 DEG C, 217 DEG C, 218 DEG C, 219 DEG C, 220 DEG C, 221 DEG C, 222 DEG C, 223 DEG C, 224 DEG C, 225 DEG C, 226 DEG C, 227 DEG C, 228 DEG C, 229 DEG C, 230 DEG C, 231 DEG C, 232 DEG C, 233 DEG C, 234 DEG C, 235 DEG C, 236 DEG C, 237 DEG C, 238 DEG C, 239 DEG C, 240 DEG C, 241 DEG C, 242 DEG C, 243 DEG C, 244 DEG C, 245 DEG C, 248 DEG C, 250 DEG C, 252 DEG C, 255 DEG C, 258 DEG C, 260 DEG C, 262 DEG C, 264 DEG C, 266 DEG C, 268 DEG C, 270 DEG C, 272 DEG C, 274 DEG C, 276 DEG C, 278 DEG C, 280 DEG C, 282 DEG C, 284 DEG C, 286 DEG C, 288 DEG C, 290 DEG C, 292 DEG C, 294 DEG C, 296 DEG C, 298 DEG C, 300 DEG C, 302 DEG C, 304 DEG C, 306 DEG C, 308 DEG C, 310 DEG C, 312 DEG C, 314 DEG C, 316 DEG C, 318 DEG C, 320 DEG C, or the arbitrary temp between them.It should be appreciated by those skilled in the art that, before shifting out from receiving container 10, in the temperature of the biomass 30 of roasting process end roasting densification, initial natural materials will be depended on, the biomass 20 of densification are immersed in the time in the flammable liquid 12 of heating, the kind of the flammable liquid 12 of use and the temperature of flammable liquid 12.
During the biomass 20 of densification are immersed in flammable liquid 12 and during roasting process, the biomass 20 of densification absorb flammable liquid 12, make the biomass 30 of the densification of the roasting produced retain the flammable liquid 12 of some absorptions.The amount of the flammable liquid 12 in biomass 30 that are that absorbed by the biomass 20 of densification and that be retained in the densification after roasting depends on some different factors, comprise, such as, the physicochemical property of starting raw material, the density of the biomass 20 of densification, the amount of starting raw material, the Immersion time of biomass 20 in flammable liquid 12 of densification, the flammable liquid 12 of use and the temperature of flammable liquid 12.As further illustrated and describe in embodiment 4 and 5, the absorption of biomass 20 pairs of flammable liquids 12 of densification will not occur with a constant speed.Compare the uptake rate roasting process deuterogenesis, flammable liquid 12 is initially absorbed with a higher rate.Such as, the flammable liquid between the biomass about 9% that the contribution ratios when roasting process starts can be the absolutely dry densification of input of every quality to about 18% w/w, or the arbitrary ratio between them, as, but be not limited to, about 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, or the arbitrary ratio between them.After the initial higher rate of the absorption of flammable liquid 12, contribution ratios declines and during roasting process, remains on a complete constant ratio for some time.The lower ratio occurred during roasting process stage casing can for the flammable liquid between the biomass about 6% of the absolutely dry densification of input of every quality to about 14% w/w, or the arbitrary ratio between them, e.g., but be not limited to, about 7%, 8%, 9%, 10%, 11%, 12%, 13%, or the arbitrary ratio between them.If find that the biomass 20 of densification are immersed in long period section in flammable liquid 12, the contribution ratios of biomass 20 pairs of flammable liquids 12 of densification reduces greatly.Such as, the ratio absorbed in the roasting process later stage can be the flammable liquid between about 2% to about 10% w/w of the biomass initial absorption ratio of the absolutely dry densification of input of every quality, or the arbitrary ratio between them, as, but be not limited to, about 3%, 4%, 5%, 6%, 7%, 8%, 9%, or the arbitrary ratio between them.If the biomass of densification 20 are the submergence a very long time in flammable liquid 12, the contribution ratios of biomass 20 pairs of flammable liquids 12 of densification also may drop to negative ratio.It seems because roasting process keeps time period of ever-increasing prolongation, some roasting process comparatively early the stage may be discharged by the flammable liquid 12 that the biomass 20 of densification absorb from the biomass 30 of the densification of roasting.As above disclosed, along with time lapse, the ratio of absorption with higher ratio, constant ratio, the lower ratio of absorption or negative ratio occur; That is, the loss of the flammable liquid caused by the biomass 20 of the densification of roasting is one or more by what depend in the amount of the physicochemical property of the temperature of flammable liquid 12, starting raw material, starting raw material, flammable liquid 12, the kind of flammable liquid 12 used and other factors.But, it is evident that, the uptake rate change of biomass 20 pairs of flammable liquids 12 of densification during roasting process, make, contribution ratios is initially higher, subsequently along with time decreased and, finally, the loss of some flammable liquids 12 absorbed in early days in this process may be caused.Find based on these, the time length of roasting process can be changed to obtain the biomass 30 of the densification of the roasting of the flammable liquid 12 being wherein absorbed with different amount.
The time quantum that the biomass 20 of densification are immersed in flammable liquid 12 may change to some extent according to different variablees, as, such as, the character of starting raw material, comprise its size and initial temperature, receive the size of container 10, for the amount of the starting raw material of roasting, the amount of flammable liquid 12, the physicochemical property of biomass 30 expectation of the kind of flammable liquid 12 and the densification of roasting, as quality, the amount being included in oil wherein, carbon content, hydrophobic property and heat energy value (BTU/ pound or GJ/t).For example, the Immersion time of biomass 20 in flammable liquid 12 of densification can change from about 2 minutes to about 120 minutes, or arbitrary time quantum between them, as, such as, from about 2 minutes to about 110 minutes, or arbitrary time quantum between them, from about 2 minutes to about 100 minutes, or arbitrary time quantum between them, from about 2 minutes to about 90 minutes, or arbitrary time quantum between them, from about 2 minutes to about 80 minutes, or arbitrary time quantum between them, from about 2 minutes to about 75 minutes, or arbitrary time quantum between them, from about 2 minutes to about 70 minutes, or arbitrary time quantum between them, from about 2 minutes to about 75 minutes, or arbitrary time quantum between them, from about 2 minutes to about 70 minutes, or arbitrary time quantum between them, from about 2 minutes to about 65 minutes, or arbitrary time quantum between them, from about 2 minutes to about 60 minutes, or arbitrary time quantum between them, from about 2 minutes to about 55 minutes, or arbitrary time quantum between them, from about 2 minutes to about 50 minutes, or arbitrary time quantum between them, from about 2 minutes to about 45 minutes, or arbitrary time quantum between them, from about 2 minutes to about 40 minutes, or arbitrary time quantum between them, from about 2 minutes to about 35 minutes, or arbitrary time quantum between them, from about 2 minutes to about 30 minutes, or arbitrary time quantum between them, from about 2 minutes to about 25 minutes, or arbitrary time quantum between them, from about 2 minutes to about 20 minutes, or arbitrary time quantum between them, from about 5 minutes to about 60 minutes, or arbitrary time quantum between them, from about 5 minutes to about 55 minutes, or arbitrary time quantum between them, from about 5 minutes to about 50 minutes, or arbitrary time quantum between them, from about 5 minutes to about 45 minutes, or arbitrary time quantum between them, from about 5 minutes to about 40 minutes, or arbitrary time quantum between them, from about 5 minutes to about 35 minutes, or arbitrary time quantum between them, from about 5 minutes to about 30 minutes, or arbitrary time quantum between them, from about 5 minutes to about 25 minutes, or arbitrary time quantum between them, from about 5 minutes to about 20 minutes, or arbitrary time quantum between them, from about 5 minutes to about 15 minutes, or arbitrary time quantum between them, or about 2 minutes, 2.5 minute, 3 minutes, 3.5 minute, 4 minutes, 4.5 minute, 5 minutes, 5.5 minute, 6 minutes, 6.5 minute, 7 minutes, 7.5 minute, 8 minutes, 8.5 minute, 9 minutes, 9.5 minute, 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, 21 minutes, 22 minutes, 23 minutes, 24 minutes, 25 minutes, 26 minutes, 27 minutes, 28 minutes, 29 minutes, 30 minutes, 32 minutes, 34 minutes, 36 minutes, 38 minutes, 40 minutes, 42 minutes, 44 minutes, 46 minutes, 48 minutes, 50 minutes, 52 minutes, 54 minutes, 56 minutes, 58 minutes, 60 minutes, or arbitrary time quantum between them.
After the biomass 20 of densification are immersed in the time expected in flammable liquid 12, from receiving the biomass 30 regaining the densification of roasting container 10.Receive in container 10 if the biomass of densification 20 are loaded directly into, then the utensil of any kind can be adopted from receiving the biomass 30 regaining the densification of roasting container 10.Preferably, the amount of the flammable liquid 12 of the biomass 30 of the densification of roasting has been removed in restriction by the utensil of use, because present method imagination re-uses flammable liquid 12.For example, this utensil can be perforate utensil, e.g., but is not limited to, and the spoon of trough of belt can be maybe a pair pliers, tweezers, fire tongs etc.If upholder 22 is received in container 10 for the biomass 20 of densification being loaded into, so upholder 22, be included in roasting wherein densification biomass 30 together with shift out from receiving container 10.

embodiment 9
Materials and methods
In order to compare when using Jie's caul-fat to implement embodiment 9 to paraffin as the oil absorption of the particle of densification during flammable liquid as flammable liquid.
In this embodiment, the granulated cork (SPF wood particle) of the densification be made up of the mixture of dragon spruce, pine and fir wood is tested.Take 250 grams of SPF wood particulate samples and weigh the wire sieve of the material for holding densification respectively.Then the material sample of densification to be loaded in this wire sieve and to measure the gross weight that this dusting cover adds the material of densification, then placing and be used for test purpose on one side.This embodiment uses the small-sized test set described in embodiment 1.Initial step is placed on by small vessels on balance and measures the net weight of this small vessels.Measure the oil (Jie's caul-fat or paraffin) of a volume and to pour in this small vessels and measure this small vessels and add the gross weight oiled, obtaining the net weight of oil thus.
The measurement one of oil completes, and just opens gas burner to assigned temperature (250 DEG C, 260 DEG C or 270 DEG C), and the temperature of monitoring oil.
Be stabilized in the temperature of expectation in oil temperature after, measure following weight: (a) small vessels adds the weight of the oil of heating; B () small vessels adds that lid that the oil of heating adds for small vessels adds the weight of the temperature sensor be inserted in this small vessels; And (c) small vessels adds that lid that the oil of heating adds for small vessels adds that the temperature sensor be inserted in this small vessels adds that 250 grams to be loaded in wire sieve and to be placed in the weight of the material sample (that is, not also being immersed in small vessels) of the densification at small vessels top.
More than measure one to complete, the wire sieve being about to the material comprising densification is immersed in the oil of heating and is stamped in the small vessels of lid, the material of densification is immersed in the time quantum (15 or 30 minutes) of specifying in the oil of heating.After the time that submergence is expected, turn off gas burner and measure the gross weight (material of dusting cover and densification is still immersed in oil) of the material of small vessels, oil, lid, temperature sensor, dusting cover and densification.Then the wire sieve wherein comprising the material of densification is shifted out from small vessels and oil, and make it above small vessels, drain about 5 minutes.Weigh the wire sieve drained wherein including the material of densification, and weigh the material of densification subsequently respectively.Shift out the material of dusting cover and densification, weighed the gross weight of small vessels, oil, lid and temperature sensor, and then then weighed small vessels respectively and add the gross weight oiled.
Then calculate the absolutely dry weight (that is, to provide the absolutely dry base of the particle of roasting) of the particle of roasting, then the absolutely dry weight of particle is compared with the loss of oil and oily absorption of the % of calculating.
(namely above process twice has been combined for each temperature, time and oil, at each different temperature and Immersion time, twice test run is completed to different types of oil of each test), each process originates in the particulate samples of 250 grams of densifications.
Result
As shown in figure 11, when using Jie's caul-fat to be used for roasting process as flammable liquid, when the temperature of Jie's caul-fat is elevated to 260 DEG C from 250 DEG C, the oil of the biomass of densification absorbs and is tending towards substantially increasing, but when then declining slightly with during the temperature calcination of 270 DEG C.The weight of the biomass of the densification of roasting also has an overall decline along with the rising of temperature seems; But, with to carry out compared with process 30 minutes (namely at 250 DEG C, compared to starting weight+8.53g, reach the final weight of 246.4g), carry out calcination process at 260 DEG C and within 30 minutes, cause the increase of weight (namely, compared to starting weight+11.48g, reach the weight of 249.35g).(namely the increase of this weight corresponds to the increase of oil absorption under this temperature-time conditions, the oil of the absolutely dry particle 21.02% of 260 DEG C of 30 minutes every mass inputs absorbs, by contrast 250 DEG C 30 minutes 16.65% oil absorb), this increase disclosing this weight is due to when the oil absorption increased when 260 DEG C of roastings 30 minutes.Small decline that when using the temperature of 270 DEG C, oil absorbs (, the oil of 15 minutes be absorbed as 16.86% and within 30 minutes, be 17.11%) also correspond to the minimizing of the weight of the biomass of the densification of roasting at this temperature (namely, 15 minutes-1.28g and 30 minute-5.47g), disclose oil further and absorb relevant to the weight of the biomass of the densification of the roasting produced.These data are also associated with the data obtained in embodiment 3 and 5.
Figure 12 shows use paraffin as obtaining similar result during flammable liquid.When the temperature of paraffin is elevated to 260 DEG C from 250 DEG C, the oil of the biomass of densification absorbs and is tending towards substantially increasing, but when when 270 DEG C of roastings, then declines.When temperature is elevated to 260 DEG C from 250 DEG C and when each time point increases Immersion time, the oil of paraffin absorbs the oil that is greater than Jie's caul-fat of advancing the speed and absorbs and advance the speed.For Jie's caul-fat, the weight along with the biomass of the densification of temperature rising roasting seems an overall reduction.But, from Jie's caul-fat, between the oil that the biomass of the weight of the biomass of the densification of roasting and the densification of roasting absorb when end of processing, seem there is no dependency.
Following Figure 13 and table 14 and 15 illustrate when use Jie caul-fat as during flammable liquid during roasting process, the ordinary loss of Jie's caul-fat is more.Except roasting at 250 DEG C, when using Jie's caul-fat or paraffin, the amount of oil loss is similar substantially, uses paraffin, when when 250 DEG C of roastings 15 minutes, the amount of the paraffin of loss was obviously less.In addition, when use paraffin as during flammable liquid at 250 DEG C between roasting 15 minutes and roasting 30 minutes, the ratio of oil loss it seems the ratio of the oil loss be significantly greater than when using Jie's caul-fat.
As shown in Figure 14, when using Jie's caul-fat instead of paraffin as flammable liquid, compared with initial biomass, the minimizing of the weight of the particle of roasting there are differences.For both, as shown in table 14 and 15 and as above describe, the weight of the particle of roasting is tending towards declining along with the increase of temperature substantially.But for Jie's caul-fat, when carrying out calcination process at 250 DEG C and 260 DEG C, the weight of the particle of roasting overweights the particle of initial densification.Only when 270 DEG C of roastings, there is the minimizing of a weight with the Particle Phase Bizet of initial densification.For paraffin, except except 250 DEG C of roastings 15 minutes, the final weight of the particle of roasting is usually lower than the starting weight of the particle of densification.Paraffin causes a larger weight minimizing usually under all time points and temperature.Be not wishing to be bound by theory, these the possibility of result due to, compared with use Jie caul-fat, biomass absorb less paraffin during roasting process.The less absorption of paraffin may be because the longer molecular chain of paraffin also may be the result of paraffin vaporator rate faster.

Immersion time in Jie's caul-fat of heating seems little with the hydrophobic performance relation of the product obtained; But these results show to compare for calcination process with using longer Immersion time (such as, 30 minutes), and the particle of the densification of the roasting of generation absorbs more water at shorter Immersion time (such as, 10 minutes) usually.
