Abstract
An efficient process for synthesizing liquefied gas includes such steps as proportioning raw materials including pentane (1000 wt. portions), dimethylether (3-4), toluene solutino of ferrocene (0.3-0.5), sodium hydroxide (0.8-1.2), and thiols (0.4-0.6), stirring while reaction laying aside, loading in tank, and pouring in steel cylinders. They are compounded in a reactor with stirrer; adding first other materials, later dimethylother. Its advantages are simple process, low cost, and high heat value of product.
Description
The present invention relates to a kind of method for making of environment protection type efficient liquefied synthetic gas, belong to organic chemical industry and fuel industry
Technical field.
In the past industry and civilian oil liquefied gas, gas when being the refining oil is stored in the pressure pan through pressurized liquefied, and decompression is used during use, but present this liquefied gas deficiency, especially side area and rural area, be badly in need of solving a kind of can safe handling, nontoxic, non-hazardous fuel liquefied gas again.
A kind of heat of employing industrial chemicals preparation that the objective of the invention is to develop at above-mentioned situation is imitated height, cost is low, easy to use, can use the method for liquid fuel free from environmental pollution again safely.
One, starting material require and the effect of starting material in prescription:
1, pentane: molecular formula C
5H
12, it is the flammable liquid that a kind of light yellow transparent nothing is pressed, pentane divides three kinds: (1) Skellysolve A, (2) iso-pentane, (3) neopentane, just be regardless of on the general industry, different, new three kinds all can use.Ingredient requirement: content is more than 85%, and proportion is below 0.63, and boiling point is 36.1 ℃, and proportion low levels more is high more.
2, ferrocene: molecular formula (C
5H
5)
2The Fe formal name used at school is that two rings luxuriant two rare bases close iron, is a kind of material of orange powder shape, and its effect is in liquefied synthetic gas: fume-eliminating energy-saving.Because it can not be directly and pentane soluble, thus before using earlier with adding again after the toluene dissolving, the dissolving ratio is 1: 3 (ferrocene 1: toluene 3).
3, sodium hydroxide: molecular formula is NaOH, claims caustic soda, caustic soda, caustic soda again, is the translucent solid of a kind of white.Sheet, granular, bulk etc. are arranged,,, increase the temperature of pentane after the heat release, make faster, the gasification more fully of pentane because the pentane boiling point is 36.1 ℃ with strong heat release after water or other liquid mixing.
4, mercaptan: molecular formula: R.SH is a kind of savory nontoxic material, and the national regulation domestic gas must add a kind of additive, in case combustion gas leaks, effect is to improve security.
5, dme: molecular formula: CH
3OCH
3Be a kind of water white compressing inflammable liquid, more stable again because the main raw material pentane is a liquid, the steel cylinder of packing into can not have gas to overflow the generation burning, so necessary with a kind of supporting agent (propellent).Put into and the main raw material pentane is fully gasified after the propellent to become just incendivity of gas, dme is to use more, a kind of supporting agent preferably in the market, it can mix arbitrarily with pentane and not become other material, its principle of work is the same with sterilant, air freshener used in the daily life, this ejects pentane unlike mist, to could realize under the effect of supporting agent that effect is to produce pressure to make gasifying pentane.
Two, compound method and prescription:
At first with ferrocene: the part by weight of toluene=1: 3 mixes, and it is standby that ferrocene is dissolved in the toluene, and ratio range is as follows:
Pentane 1000 (weight part)
Dme 3-4 (weight part)
Ferrocene toluene solution 0.3-0.5 (weight part)
Sodium hydroxide 0.8-1.2 (weight part)
Mercaptan 0.4-0.6 weight part
Best proportioning:
Pentane 1000 (weight part)
Dme 3.5 (weight part)
Ferrocene toluene solution 0.4 (weight part)
Sodium hydroxide 1.0 (weight part)
Mercaptan 0.5 (weight part)
Preparation steps:
Take by weighing raw material in the retort of belt stirrer by prescription, the normal temperature and pressure preparation, add pentane earlier, add the ferrocene toluene solution again, add sodium hydroxide, mercaptan again, add dme at last, stir, leave standstill more than half an hour, be stored in the basin, extract with pipeline from basin, can gets final product to steel cylinder.
Processing unit:
The building-up reactions jar, see Fig. 2-3, Fig. 2 equipment is used for preparing big in batches liquefied gas, Fig. 3 equipment is used for preparing little in batches liquefied gas, can can reduce cost without whipping device, this kind retort is the generalization construction equipment, with Fig. 2 is example, by the motor (3) and step-down gear (4) formation of tank body (8), cover (7), ring flange (15), foot rest (12) and drive agitator (13,14); Cover (7) part is equipped with safety valve (1), tensimeter (2), opening for feed (5), little ingredients mouth (6); One side of tank body (9) is equipped with liquid level meter, can observe tank level at any time; Pot bottom has waste liquid outlet (11), if preparing liquefied gas can use Fig. 3 equipment in a small amount, tank body (8) is a monoblock type, and retort is belt stirrer not, is suitable for the small serial production liquefied gas, and peasant household oneself also can make, but must take care, and keeps fire away.
The present invention's advantage and effect compared with the prior art is as follows:
Oil liquefied gas in the past, complex process, the cost height, investment is big, and this scale of the project is changeable, and technology is simple, less investment, cost is low, and the combustion heat value height of product can reach 49000 kilojoules/kg, and safe in utilization, nontoxic.
Description of drawings:
Fig. 1 is a process flow sheet of the present invention;
Fig. 2 is the synthetic anti-jar structure of processing unit of the present invention;
Fig. 3 is the simplified apparatus organigram of Fig. 2;
Fig. 4 arranges synoptic diagram for plant area.
Embodiment:
1, technical process, see Fig. 1,5 of raw materials devices are arranged, stock 5 kinds of raw materials, can open respectively or close, grasp successively reinforced and amount, to retort, reacted liquefied gas enters basin and stores, can flow between the finished product canning cart, bottle and dispatch from the factory, if small serial production, these technologies can be simplified.
2, factory's cloth is arranged, sees shown in Figure 4ly, and for safety, starting material part and building-up reactions jar and storage of finished products and racking room all will have the isolation strip.Factory building is away from outside 100 meters of the Residential areass, tower structure, standing fire control equipment.
