Description
Technical field
The invention belongs to the bio-oil synthesis technical field, particularly a kind of technology of producing biologic diesel oil through combination of different lipases is used in combination the lipase of different catalytic performances, is used for the novel process that the catalysis of renewable glyceride stock transforms biodiesel synthesis.
Background technology
By the long chain fatty acid ester class material that transesterification reaction generates, is a kind of novel pollution-free renewable energy source by the bio-oil raw material, is called as biofuel.Its combustionproperty can be that diesel oil matches in excellence or beauty with traditional oil, and research of biofuel at present and application have been subjected to widely to be paid close attention to.
Biofuel mainly is to use chemical method production at present, promptly uses animal-plant oil and some low-carbon alcohol (methyl alcohol or ethanol) to carry out transesterification reaction under alkali or an acidic catalyst effect, generates corresponding fatty acid methyl ester or ethyl ester.Chemical method prepares biofuel and has some unavoidable problem, and discharging causes secondary pollution etc. to environment easily as spent acid (alkali) liquid.Because free fatty acids and the less water of utilizing the biological enzyme biodiesel synthesis to have in reaction conditions gentleness, non-pollutant discharge, the glyceride stock do not influence advantages such as enzymatic reaction, meet the developing direction of Green Chemistry, thereby are subject to people's attention day by day.But also there are some problem demanding prompt solutions in enzyme process biodiesel synthesis technology, and is too high as the cost of enzyme, and enzymatic conversion method glyceride stock biodiesel synthesis yield is relatively low etc.So the biological enzyme technology that exploitation is cheap, the yield that reduces biological enzyme use cost and raising biological enzyme biodiesel synthesis is to realize the key of biological enzyme industrialization production biofuel.
The biological enzyme glyceride stock of being reported at present that utilizes carries out in the building-up process of biofuel, generally all is to use the single fat enzyme to carry out the conversion of glyceride stock.Utilize this single enzyme method technique to carry out the synthetic of biofuel, the yield of general biofuel is relatively low.
Summary of the invention
The objective of the invention is to propose a kind of technology of producing biologic diesel oil through combination of different lipases; utilize the catalysis characteristics of different lipase; especially the substrate specificity of lipase and position specific; two or more lipase are used in combination; be used for the catalyzed oil fat raw material with short chain alcohol such as methyl alcohol and other acyl acceptor biodiesel synthesis that reacts; thereby on the basis that obtains higher bio-diesel yield, effectively reduce the biological enzyme cost.
The 2-5 kind lipase that the present invention is different with catalytic performance is used in combination, and utilizes the catalysis characteristics of different lipase, and glyceride stock is effectively transformed the generation biofuel.It is characterized in that:
The lipase that performance is different mixes use or separately " polyphone " use, especially will have 1, and the lipase of 3-position specific is used in combination with the lipase that does not have position specific; Be used for the reaction of catalyzed oil fat raw material and short chain alcohol and carry out the preparation of biofuel.The reaction mol ratio of short chain alcohol and glyceride stock is 1: 1-5: 1, and be reflected in the biochemical reactor that is suitable for enzymic catalytic reaction and carry out, temperature of reaction is 30 ℃-50 ℃; Reaction can be intermittently batch be carried out or is carried out continuously, and reaction system is a solvent-free system, contains the system or the organic reaction medium system of organic solvent, and organic solvent comprises the trimethyl carbinol, methyl acetate, ethyl acetate, hexane or acetone.Reaction process can have water absorber or not have water absorber.This novel process can almost completely transform the generation biofuel with glyceride stock fast under the situation of using less enzyme amount.
Lipase of the present invention is microbial lipase, preferentially comprises immobilized lipase Lipozyme TL (deriving from Thermomyces lanuginosus), Lipozyme RM (deriving from Rhizomucor miehe).Novozym435 (deriving from Candida antarctic).The immobilized lipase that derives from Candida antarctic comprises Novozym435, the immobilized lipase that derives from Thermomyces lanuginosus comprises Lipozyme TL, and the immobilized lipase that derives from Rhizomucor miehei is drawn together Lipozyme RM.
Grease of the present invention is that bio-oil comprises Vegetable oil lipoprotein, animal grease, waste edible oil or oil refining pin material.
Vegetable oil lipoprotein of the present invention is Viscotrol C, rapeseed oil, soybean oil, peanut oil, Semen Maydis oil, Oleum Gossypii semen, Rice pollard oil or algae grease.
Animal grease of the present invention is fish oil, lard.
Short chain alcohol of the present invention is methyl alcohol, ethanol, propyl alcohol, butanols or amylalcohol.
Other acyl acceptor of the present invention is short-chain aliphatic ester RCOOR ', and wherein R and R ' are for having the alkyl of 1-5 carbon atom.
" polyphone " of the present invention uses and is meant that reactant transforms through lipase 1 earlier, transforms or lipase 3 conversions through lipase 2 again.
The present invention is that the lipase with different catalytic performances effectively is used in combination, be used to transform the preparation that the renewable oils fat raw material carries out biofuel, its beneficial effect is when using less enzyme amount (also promptly effectively reducing the biological enzyme cost), can obtain the biofuel of high yield.
