Abstract
The invention provides biodiesel based fuel oil which comprises the following components by weight: 50-80 percent of crude biodiesel, 4-35 percent of compound emulsifying agent, and one or two mixture of water and methanol, wherein the compound emulsifying agent is the mixture of the two types of materials, the first-type material is one or the mixture of a plurality of oleic acid, palmitoleic acid, naphthenic acid, aliphatic amine polyethenoxy ether with C atomicity being 40-100, dehydration sorbitan fatty acid ester with C atomicity being 40-100, polyoxyethylenec dehydration sorbitan fatty acid ester with C atomicity being 40-100; the second-type material is one or the mixture of a plurality of monoethanol amine, diethanolameine, trolamine, diglycol amine, 1-octanol and tertiary butyl alcohol. The preparation method is as follows: the mixtures are mixed according to the percent by weight and are mixed uniformly so as to obtain transparent solution. The fuel oil has good stability, non layering for a long time, no discolor and no turbidity, and is directly prepared by adopting the crude biodiesel. Methanol or water or the mixture of the water and the methanol is added, thus the consumption of the biodiesel is saved.
Description
Technical field
The invention belongs to the biodiesel technology field, be specifically related to a kind of oil fuel based on biofuel and preparation method thereof.
Background technology
The biofuel compounded technology comes out existing decades, but does not obtain promotion and application widely so far, and its reason is that there are a lot of shortcomings in the composite biodiesel that prior art is produced: 1. poor stability, preservation period is short.Composite biodiesel majority of countries in the world development at present be the milk sap of white or yellow-white, and its particle diameter is at 0.01-0.1mm, poor stability, and preservation period is short, so can not have enough to meet the need as tank oil, makes troubles to promoting the use of.The equipment complexity, investment is big, energy consumption is high.3. emulsification cost height.Though oil-saving effect is preferably arranged, fuel-economizing does not save money, and economic benefit is little, as CN101250431A micro-emulsified biological diesel and preparation method thereof.
Biofuel is economic, eco-friendly alternative fuel.Biofuel is clean CO as the major advantage of recyclable fuel
2Discharging reduces, and the exhaust gas emission of oxysulfide, particulate matter and carbon monoxide also reduces, but the calorific value of itself is lower than petrifaction diesel, and resistance to low temperature is also not as petrifaction diesel.
The research of biofuel emulsive is arranged at present, promptly under the effect of emulsifying agent, in biofuel, mix a certain amount of first alcohol and water, reach the purpose that reduces cost, but, still need consume the equipment and the energy that needs in the biofuel treating process economically because the raw material that uses is a refining biodiesel.And the raw material that the present invention adopts is a coarse biodiesel, does not promptly need coarse biodiesel is carried out any refining and sepn process, has not only reduced the loss of process, and has reduced the consumption of the energy in facility investment and the process.The calorific value of the biofuel of producing is generally about 38KJ/g.
Summary of the invention
The calorific value that the present invention is directed to the prior art existence is low, needs use refining biodiesel, the shortcoming of poor stability, a kind of biodiesel based fuel oil and preparation method thereof is provided, the biofuel of preparation has good stability, calorific value height, the advantage of using the coarse biodiesel preparation to get final product.
The present invention adopts following technical scheme: a kind of biodiesel based fuel oil, form by following material, by weight percentage:
Coarse biodiesel 50-80%
