Abstract
The present invention provides process of producing biodiesel oil (fatty methyl ester) with vegetable oil fatty acid. The production process includes the following steps: 1. dewatering vegetable oil in a reaction tower at 80-120 deg.c and 0.3-0.5 KPa to obtain material oil with water content not more than 1.4 %; 2. heating the material oil at 320-340 deg.c in a heating furnace and distilling in a distilling tower at the temperature not lower than 310 deg.c for 1-2 hr; 3. fractioning the distilled oil and vapor in a rectifying tower and filtering the obtain biodiesel oil in a filtering tower; and 4. cooling the filtered biodiesel oil with cooling water at 30-50 deg.c to obtain biodiesel oil product. The production process has high conversion rate, less catalyst, less additives and other features.
Description
Technical field
The present invention relates to a kind ofly produce the method for fatty acid methyl ester (biofuel), belong to field of grease chemical technology with vegetable fatty acids.
Background technology
In disclosed technology, CN1382762A is described, and it is under an acidic catalyst existence condition, and the aste vegetable oil and animal fat of various different acid numbers is carried out alcoholysis and esterification, after passing through a series of processing then, produce the method for fatty acid methyl ester with adding soda ash distillatory method.CN1724613 is described, and it is that reaction finishes to reclaim earlier methyl alcohol by transesterification reaction of raw material employing, passes through the technology of steam distillation refining biodiesel again.The fatty acid methyl ester of producing by existing known technology method need add a large amount of catalyzer, additive etc., is difficult for extracting from last finished product again, has influenced the purity of fatty acid methyl ester.
Summary of the invention
Characteristics such as technical problem to be solved by this invention is that a kind of method that can utilize vegetable fatty acids to produce fatty acid methyl ester (biofuel) economically will be provided, and this production method has the transformation efficiency height, and catalyzer, additive are few.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
(1) earlier vegetables oil is dewatered in reaction tower, temperature is 80 ℃-120 ℃, and pressure is 0.3-0.5 kPa, makes the water ratio of vegetables oil be no more than 1.4, makes stock oil;
(2) stock oil is heated to 360 ℃-380 ℃ in process furnace, enters in the distillation tower and distill, the temperature of distillation tower can not be lower than 310 ℃, and the temperature of cat head is between 320 ℃-340 ℃;
(3) after the lipid acid oil plant distilled 1-2 hour in distillation tower, distilled oil vapour carried out cut via rectifying tower, and gained diesel oil enters filtration tank and filters;
(4) diesel oil after the filtration enters the cooling tower cooling, and coolant water temperature is between 30 ℃-50 ℃, and biofuel gets product.
Advantage of the present invention is: method is simple, cost is low, reaction process is short, purity safe and reliable, easy to operate, gained fatty acid methyl ester (biofuel) is high.
