Technical field

On the whole, the present invention relates to the engine fuel field.More specifically, the present invention relates to by a small amount of petrochemical diesel fuel combination volume depleted vegetables or animal oil, and further with the composition of the made mixing engine fuel of the mixture upgrading of stablizing chemical agent.The gained compound fuel is specially adapted to the application by diesel motor, also uses applicable to other fuel and heat energy.The present invention further is applicable to as mechanical internal lubricant.The present invention also provides the relevant necessary method of this compound fuel of making.

Background technology

Because the supply of inorganic hydrocarbon fuel reduces day by day, exploitation has been instant society and economic problem by renewable resource deutero-alternative fuel.Natural, biosynthesizing oils especially by plant seed or by the oils that other plant constituent or plant waste obtained, are represented the feasible terms of settlement of supply of fuel problem.Except processing and transportation cost, but these natural fuel can not have influence on the usage quantity of fossil fuel.

Moreover, consider global warming, plant oil fuel this as " neutral carbon " (carbon-neutral) and in burning the time do not increase atmospheric environment percent of greenhouse gases or concentration of carbon dioxide substantially.Vegetables oil is finally produced by photosynthesis, uses in the atmosphere carbonic acid gas as carbon source, so the burning of these oils mainly makes carbon circulate in environment and do not increase the total carbon burden.For actual purpose, be supplied as limited oil fuel with respect to geology, plant oil fuel is reproducible certainly.

Waste vegetable oil (Waste vegetable oil (WVO)) is rich in energy derive for what can obtain in a large number, is derived from food mfg industry and uses vegetables oil as fried dose byproduct.For example, wherein a kind of common WVO, the color that is produced during as fried media because of it is called " butter " YG.Other exhausted frying oil or fat are as derived from the butter of beef fat and derived from the lard of pork fat, because its high energy content also is potential fuel.WVO, YG, lard and exhausted butter need be regenerated or further be used in and be prevented to pile up and environmental pollution.The purposes attractive, that meet economy that increases gradually of these wastes is the raw materials that act as a fuel.

Biofuel (biodiesel) has been common in commerce, and the vegetables oil that comprises WVO for a kind of employing is as an example that is the alternative fuel of raw material.Biofuel produces the recyclable fuel of reproducible methylethyl fatty acid ester for using basic catalyst by the transesterification reaction (transesterification) of vegetables oil.These ester classes subsequently by single from producing cleaning by reaction mixture, being rich in the diesel oil fuel material of energy.

Generally speaking, the oil that biodiesel fuel mixes as fuel of diesel oil or No. two fuel of diesel oil is that main diesel oil fuel mixes, manufacturing has acceptable performance and stores the compound fuel (general-quality criteria of diesel oil fuel is formulated by the ASTM of american society for testing and materials, and the standard of diesel oil fuel is ASTM 975) of quality.For example, B20 is for mixing the composite biodiesel fuel of 20% biofuel and 80% petrifaction diesel (volume ratio).Similarly, the B50 biofuel contains 50% biofuel (volume ratio).

B20 is the diesel oil fuel of high expectations, and more commercialization recently has good cetane value (cetane rating) and other advantageous feature.The B20 sulfur-bearing is less than No. two fuel of diesel oil, is mainly no sulphur because of giving birth to the matter fuel composition, so B20 and the burning of other biofuel compounding mixture are all more cleaned than No. two fuel of diesel oil itself.B20 meet be in particular biofuel quality and performance fixed ASTM standard 6751.

Yet biodiesel fuel has its shortcoming.Become known for making pure composition, the especially methyl alcohol of biofuel, have toxicity and palpus special operational.These pure composition highly volatiles and highly inflammable have explosivity.The reaction basic catalyst, sodium hydroxide commonly used also is highly corrosive and nocuous material, needs special container and careful disposal.In addition, the relatively avirulent by product of transesterification reaction, glycerine need store and dispose.

The present invention is for to respond above-mentioned shortcoming.Main purpose of the present invention is for a kind of more burning of cleaning is provided, and is more efficient, effective fuel for diesel engines and other application more cheaply.Extend the compound fuel mixture that makes up with the relative a small amount of of petrochemical diesel fuel for vegetables oil and animal oils.Vegetables oil and animal oils are preferably waste oils.For acceptable fuel characteristic is provided, this compound fuel further mixes with the compounding mixture of chemical modifier in a small amount, is generically and collectively referred to as " stablizer " mix.

The mixture of being finished has excellent lubrication character.Compound fuel is the more inexpensive manufacturing and the disadvantageous by product of environment of its manufacturing processed generation minimum quantity than biofuel.This specification sheets discloses the composition and the manufacture method of novel compound fuel and lubricant.

Summary of the invention
