Description
Technical field
The technical field that the invention belongs to fuel, is specifically related to a kind of biological composite diesel oil and preparation method thereof.
Background technology
Because oil price rises steadily, petroleum resources are petered out; the whole world is all faced with energy starved crisis; simultaneously along with the raising of people's living standard and the enhancing of environmental protection consciousness; people recognize the air-polluting seriousness that oil causes as fuel gradually; particularly the frequent appearance of photo-chemical smog, acid rain has caused great harm to HUMAN HEALTH, the Greenhouse effect havoc that CO2 produces the eubiosis.Therefore, international petroleum tissue thinks that a kind of new energy of exploitation comes petroleum replacing fuel own extremely urgent, large quantity research shows, biofuel is one of most important clean fuel, it is the most rising alternative fuels for diesel engine, its major advantage is: biodegradable, renewable resources, nontoxic, discharge amount of exhaust gas is little etc., belongs to environmentally friendly fuel, is the petroleum diesel surrogate of high-quality.Biofuel is typical case's " green energy resource ", greatly develops biofuel sustainable economic development, propelling energy substitution are alleviated to environmental stress, controls urban atmospheric pollution and has important strategic importance.
Biofuel both can be used as a kind of biofuel, can be used as again diesel-dope, can be for any diesel engine.The biofuel of having developed is at present mainly the fatty acid monoester that adopts animal-plant oil and common monohydroxy-alcohol (methyl alcohol, ethanol, propyl alcohol and butanols) to obtain by transesterification reaction.But, because its oxygen level is low, make diesel emission performance be difficult to significantly be improved.
