Abstract
The present invention discloses one kind of biofuel oil and its preparation process. The biofuel oil consists of diesel oil, fatty acid, water, modifier A and modifier B in certain weight proportion. Its preparation process includes the first mixing diesel oil, fatty acid and water and heating to 50-90 deg.c; and the subsequent adding modifier A and modifier B and stirring for 5-10 min to obtain the biofuel oil product. The biofuel oil of the present invention has low cost, no pollution, environment friendship, and other advantages.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of bio-fuel-oil and preparation method thereof.
Background technology
Diesel oil occupies very high share as a kind of important refining of petroleum product in various countries' fuel structure, be the major impetus fuel of many oversize vehicles (as truck, oil engine and generator etc.), and it is big to have power, advantages such as low price.Along with the quickening of vehicle diesel oil trend in the world wide, the demand of following diesel oil can be increasing, and the raising of exhausted day by day and people's environmental consciousness of petroleum resources has promoted countries in the world to accelerate the exploitation paces of diesel oil alternative fuel greatly.
Also there are many problems in diesel oil in application process, for example efficiency of combustion is low, serious to atmospheric pollution, and it is high to produce a large amount of granule dust, CO2 emissions.
Biofuel is studied more as a kind of fuel of alternative diesel oil at present.Biofuel is that fatty acid methyl ester is a kind of oxygen clean fuel that contains, because it has the rate of combustion height, pollutes advantages such as few, renewable, by people are paid close attention to.Biofuel mainly is to use chemical method production at present, promptly uses animal and plant grease and low-carbon alcohol such as methyl alcohol or ethanol to carry out transesterification under acid or basic catalyst and high temperature (230～250 ℃), generates corresponding fatty acid methyl ester or ethyl ester.
But the chemical method biodiesel synthesis has following shortcoming: complex process, color and luster are dark, and since in the fat unsaturated fatty acids at high temperature apt to deteriorate, esterification products is difficult to reclaim, the cost height, generative process has waste lye discharging etc.
At present the subject matter that exists of biofuel is the cost height, and according to statistics, 75% of biodiesel manufacture diesel oil is raw materials cost, is the key that can biofuel practicability thereby therefore adopt cheap raw material and improve that transformation efficiency reduces cost.It is that the power-equipment of fuel is more that China adopts diesel oil at present, and very fast to the demand growth of diesel oil, there are abundant Vegetable oil lipoprotein and animal grease resource in China, and annual soya-bean oil output reaches 6,000 ten thousand tons, if well utilize, very big market potential is arranged.
Summary of the invention
The objective of the invention is to the shortcoming that exists at above-mentioned existing diesel oil and biofuel, a kind of environmental protection, rate of combustion height, bio-fuel-oil that price is low are provided.This bio-fuel-oil performance is similar to diesel oil, and it is simple to have preparation technology, cheap, the economic worth advantages of higher.
Another object of the present invention is to provide the preparation method of this bio-fuel-oil.
For achieving the above object, the present invention has taked following technical scheme:
A kind of bio-fuel-oil is characterized in that being made up of following component and weight percentage:
Petrifaction diesel 45～55%
Lipid acid 10～24%
Water 21～40%
Modifier A 0.01～3%
Properties-correcting agent B 0.01～2%.
Described petrifaction diesel can be the petrifaction diesel or the kerosene of various models;
Above-mentioned lipid acid is animal and plant lipid acid; As fatty acid ester, erucic acid quasi-grease, castor oil or the animals and plants compound lard etc. of animal grease, linolic acid, linolenic oil, oleic acid, α-oleum lini, sodium laurate grease, glycerine, can be one or more mixture wherein.
Above-mentioned modifier A is a tensio-active agent, as aliphatic acid polyethenoxy ether, polyoxyethylene glycol Octyl Ether, fatty diglycollic amide, polyoxyethylene alkylphenol ether, polyoxyethylene carboxylate, alkylol amide, alkyl benzene sulfonate, sorbitan list olein, soya-bean oil soap matter or the like, can be one or more mixture wherein.
Above-mentioned properties-correcting agent B is that sodium laurylsulfonate, lipid acid copper, silicone oil, alkyl nitric acid are dead drunk, nonyl ethers or dodecyl polyethylene oxide ether or the like, can be one or more mixture wherein.
Bio-fuel-oil of the present invention can prepare by the following method:
(1) in proportion petrifaction diesel, lipid acid, water are mixed, be heated to 50～90 ℃; And then add modifier A and properties-correcting agent B, stir and promptly generated product in 5～10 minutes.
(2) in proportion petrifaction diesel, lipid acid, water and properties-correcting agent B are mixed, be heated to 50～90 ℃; And then the adding modifier A, stir and promptly generated product in 5～10 minutes.
Compared with the prior art, the present invention has following beneficial effect:
1, bio-fuel-oil of the present invention uses lipid acid to do auxiliary material, and fatty acid source is wide, and price is low, does not produce new source of pollution;
2, utilize water as reaction raw materials, price is low, and is pollution-free;
3, not stratified in the preparation-obtained biofuel 1 year, the calorific value height, colourity and quality index are similar to crude oil;
4, reduce black smoke significantly, the pollution of improving the ecological environment, dustiness reduces more than 50% than crude oil;
5, rate of combustion height, facility investment is low, and is easy to operate, and floor space is little.
