Description
Technical field
The present invention relates to a kind of sewer oil biofuel novel process processed, be specifically related to a kind of enzyme technology that utilizes sewer oil is converted into bio oil, belong to biofuel production technical field.
Background technology
Sewer oil, all kinds of poor quality oils that general reference exists in life, as the edible oil reclaiming, the frying oil of Reusability etc.Sewer oil is a kind of quality extreme difference, extremely antihygienic inedible oil.Edible once " sewer oil ", it can destroy people's white cell and alimentary canal mucous membrane, causes food poisoning, even carcinogenic serious consequence.So " sewer oil " forbidden for edible oil field." sewer oil " backflow dining table is a thing of making us beating one's brains, and best terms of settlement is carried out recycle exactly, turns waste into wealth.
Biofuel, fatty acid ester, is a kind of containing oxygen clean fuel, by rapeseed oil, soybean oil, recovery culinary art oil, the fat cracking of animal wet goods renewable oils or transesterification reaction, is made.Biofuel is biodegradable, nontoxic, burning is complete, as the mineral diesel surrogate of high-quality, is typical " green energy resource ".The sewer oil of take is prepared biofuel as raw material, has advanced the rational utilization of sewer oil, not only prevents that sewer oil from entering food chain, promotes again the development of biofuel, has embodied higher economic benefit, environmental benefit and social benefit.According to statistics, the sewer oil that the annual catering trade in domestic city produces is up to 5,000,000 t.Within 2012, < < " 12 " national strategy new industry development program > > proposes, to the year ends 2015, whole nation biomass power generation installation reaches 1 300 ten thousand kw, biological flue gas year utilization reach 30,000,000,000 m
3, solid forming biomass fuel year utilization reaches 1,000 ten thousand t, biological liquid fuel year utilization reach 5,000,000 t.
Sewer oil biofuel processed can realize by catalytic cracking solution, ester-interchange method and ionic liquid method.Catalytic pyrolysis refers under catalyzer, hot conditions, and the triglyceride level of take is prepared an approach of biofuel as raw material, and fundamental change has occurred the product composition of catalytic pyrolysis; Ester-interchange method is the current the most frequently used method of biofuel of preparing, according to there being the type transesterify of catalyst-free and catalyzer can be divided into chemical catalysis, enzyme catalysis method and supercritical methanol technology; Ionic liquid is a kind of novel reusable green solvent, have vapour pressure, thermostability that reactive behavior is high, extremely low high, be easy to the advantages such as separated, therefore, study ionic liquid-catalyzed reaction and prepare biofuel and have important theory significance and actual application value, the research for ionic liquid is main mainly with glyoxaline ion liquid at present.Catalytic cracking solution energy consumption is large, by product pair, and transformation efficiency is low; Traditional acid catalyzed process and base catalysis method, require alcohol excessive, need have corresponding alcohol retrieving arrangement, complex process, and energy consumption and cost are high; The research of ionic liquid method is still immature, and cost is high, is also unsuitable in industrial extensive use; Enzyme catalysis method is a kind of new process for cleanly preparing, and advantage is to have that mild condition, alcohol consumption are little, non-pollution discharge.Enzyme catalysis method does not have to raw material that selectivity, energy consumption are low, environmental friendliness, is the focus of Recent study.The present invention is directed to that the normal energy consumption existing of present sewer oil biofuel processed is high, disposal of pollutants serious, to many, the inferior problem of low conversion rate of raw material restriction, utilize lipase as catalyzer, carry out sewer oil and methyl alcohol transesterification reaction generation biofuel occurs under the catalysis of lipase.
Summary of the invention
The object of this invention is to provide a kind of sewer oil biofuel novel process processed, this is simple for process, to equipment and raw material without particular requirement, and have that mild condition, alcohol consumption are little, non-pollution discharge, transformation efficiency advantages of higher.
In order to address the above problem, the technical solution adopted in the present invention is:
A sewer oil biofuel novel process processed, comprises the following steps:
A. pre-treatment: the sewer oil of recovery is heated to 60 ~ 80 ℃, carries out sedimentation removing foreign matter;
B. raw material mixes: by weight part, be that the methyl alcohol of 80 ~ 90 parts and the sewer oil of 20 ~ 30 parts mix, under the condition of 40 ~ 50 ℃, stir 1 ~ 2h;
C. transesterification reaction: the addition of enzyme is 1 ~ 5%, reacts 18 ~ 24h under the condition of 30 ~ 40 ℃;
D. reclaim: after having reacted, by the standing 2 ~ 3h of reaction solution, required biofuel is contained on upper strata, emits lower floor's liquid, to upper strata reaction solution Distillation recovery methyl alcohol, obtains biofuel;
Described steps A, its preferably processing parameter be 75 ℃;
Described step B, its preferably processing parameter for being that the sewer oil of the methyl alcohol of 80 parts and 20 parts mixes by weight part, under the condition of 50 ℃, stir 2h;
Described step B, the water content of the methyl alcohol of use is lower than 5%;
Described step C, the enzyme of use is neutral lipase;
Described step C, the addition that its good processing parameter is enzyme is 5%.
The present invention with respect to the beneficial effect of prior art is:
The present invention utilizes enzyme technology that sewer oil is converted into bio oil, and mild condition, alcohol consumption are little, non-pollution discharge, and does not have selectivity, energy consumption low, environmentally friendly to raw material, is a kind of effective ways that sewer oil are prepared into biofuel; Technique of the present invention is simple, and operational safety is convenient to suitability for industrialized production.
