Description
Technical field
The present invention relates to a kind of technology that improves production of biodiesel efficient, reduces production costs, is the preparation method of bio-diesel oil that raw material production can substitute the petroleum diesel product with natural animal-plant grease (butter, lard, soybean oil, rapeseed oil, peanut oil, Oleum Helianthi, Viscotrol C, rice bran wet goods), plant oil leftover (alkali refining soap stock, hydrated oil foot etc.), waste grease (frying oil, swill oil, acidifying wet goods) particularly.
Background technology
In recent years, along with the exhausted day by day and human of fossil energy rises to the rapid of fuel energy demand, the alternative fuel energy of development of new is all being accelerated in countries in the world.Bioenergy comprises fuel alcohol, biological hydrogen production and biofuel, has obtained people's attention with its good recyclability.Especially biofuel, its combustionproperty be at all no less than petroleum diesel, and can be directly used in petroleum diesel fields such as diesel engine, is considered to the substitute of petroleum diesel.Biofuel has the following advantages: poisonless biological degradable, and the cetane value height, sulfide, CO (carbon monoxide converter) emission are few, and the carbon of its discharging compares with petroleum diesel from atmosphere, can reduce emission amount of carbon dioxide.Therefore, biofuel is a kind of renewable environment-friendly fuel energy.
The suitability for industrialized production of biofuel and be applied in the history that more than ten years have abroad been arranged, production technology is quite ripe, and industrial scale is also in continuous expansion.Countries in the world are in order to tackle the energy dilemma that 21 century is about to appearance; all successively entered field of biodiesel oil; and strengthen biodiesel technology exploitation and industrial input; formulation helps the agricultural policy and the tax policy that the biofuel industry develops in a healthy way, and the turnout of whole world biofuel is increased sharply.The target that European Union promotes biofuel is: the biofuel share of market reached 5.75% in 2010, and the year two thousand twenty reaches 20%; American energy policy method determines that the occupation rate of U.S.'s non-petroleum fuel in 2010 will bring up to 30%, and this bring vast potential for future development can for undoubtedly the biofuel industry.Current, there are countries such as Thailand, Korea S, Bulgaria, Philippines and India to build up the biofuel factory of oneself again.
China's production of biodiesel still is in the elementary development phase, now existing Fujian brilliance, the ancient China fir in Sichuan and Hainan are just built up production capacity respectively with three companies and are surpassed 10,000 ton/year small-sized biofuel factory, but since technology and cost aspect also fail to be promoted rapidly.Domestic patent application about biodiesel manufacture at present exists that long reaction time, reaction conversion ratio are not high, energy consumption is high, the high deficiency of production cost, can't be extensive use of in commercially producing.
Summary of the invention
The objective of the invention is to the deficiency at the prior art scheme, adopt the intensified by ultrasonic wave technology, provide a kind of and be suitable for commercially producing, can reduce production costs, what can alleviate environmental pollution simultaneously is the feedstock production method of bio-diesel oil with the waste grease.
The present invention finishes above-mentioned purpose by the following technical programs.This preparation method of bio-diesel oil comprises the steps: stock oil through distillation dehydration, and water content is reduced to below 0.06%; Dehydrated raw material oil enters ultrasonic transesterification reactor reaction with methyl alcohol and mixture of catalysts, keeping the mol ratio of methyl alcohol and stock oil is 3: 1～20: 1, the catalyst quality percentage is 0.1～1%, temperature of reaction is controlled at 20-64 ℃, ultrasonic frequency is 18000～4000000Hz, and power is controlled at 30～1000W; After reaction finishes, ester exchange offspring enters the methyl alcohol distiller, the methanol eddy that steams is gone into reactor cycles and is used, reaction product behind the steaming methyl alcohol enters separator, glycerine and biofuel are separated, and isolated biofuel is removed catalyzer, saponified, moisture and methyl alcohol through neutralization, washing, continuous still battery mutually again, further purifies then and obtains high purity, promptly＞99.6wt.%, the biofuel product; Glycerine obtains the glycerine byproduct of required purity through purification.
The effect that the present invention is useful: adopt production technique of the present invention, can prepare highly purified biofuel product, and technology is simple, energy consumption is low, transformation efficiency is high, production cost is low, is suitable for commercially producing.
Embodiment:
Below in conjunction with embodiment the present invention is further described, preparation method of bio-diesel oil of the present invention thes contents are as follows:
1) coarse raw materials enters the stock oil basin after mechanical removal of impurities, squeezes into the flasher dehydration by pump again, and temperature is 100～150 ℃, 30 minutes time; Dehydrated raw material oil enters ultrasonic transesterification reactor through interchanger, adds methyl alcohol and catalyzer, maintains the temperature at 20～64 ℃, opens ultrasonic wave and carries out transesterification reaction; Reacted ester exchange offspring enters the methyl alcohol distiller, and the methanol eddy that steams is gone into reactor cycles and used, and the reaction product behind the steaming methyl alcohol enters continuous separator, and glycerine and biofuel are separated; Separating obtained biofuel enters neutralizer mutually, remove that catalyzer is laggard goes into water scrubber, enter thin-film evaporator after the washing, slough methyl alcohol and moisture, again after separating removal of impurities by being pumped into product storage tank, isolated glycerine is through dewatering, obtain behind the separating methanol glycerine byproduct of required purity; The raffinate that neutralize, wash, evaporation produces enters the use of distillation tower recovery methanol loop after collecting.
2) the used stock oil of the present invention both can be the natural animal-plant grease, also can be plant oil leftover or discarded food oils, can also be its mixture.
3) the present invention adopts dissimilar catalyzer according to the height of free fatty acid content in the stock oil, adopts basic catalyst when free fatty acid content is low, as NaOH, KOH, Na
2CO
3Deng, adopt an acidic catalyst when free fatty acid content is high, as sulfuric acid, hydrochloric acid, phosphoric acid, organic acid, superpower solid acid, strong acid ion exchange resin etc.
4) the present invention is the glycerin fatty acid ester that utilizes in the animal-plant oil, under ultrasonic wave and catalyst action, carry out transesterification reaction and generate biofuel with methyl alcohol, i.e. and fatty acid methyl ester, its chemical equation is as follows:
This reaction is reversible reaction, and the consumption that increases reactant methanol can promote reaction to develop towards the positive reaction direction, and 6: 1 molar ratio of methanol to oil can obtain speed of reaction and reaction conversion ratio faster.The present invention is adopting under the ultrasonic field intensified condition, transesterify speed and transformation efficiency all are significantly improved, reacted 10 minutes, transformation efficiency is just up to 99%, this may be because the ultrasonic cavitation effect has changed the physico-chemical property of reaction mixture, thereby increased the contact area of reactant, improved speed of reaction, also changed the equilibrium conversion of transesterification reaction simultaneously.
5) methyl esters of the present invention purifies and adopts the thin-film evaporator continuous still battery earlier, excessively go bad to prevent that product is heated, product steams after interchanger is cooled to below 30 ℃, and is good to guarantee product color, be further purified, the main quality index of prepared biofuel product is as follows again:
