The environment-friendly fuel obtained by the invention has the characteristics of high cetane number, low sulphur content, low ash content, energy saving and environmental friendliness; a production and preparation process is simple, safe, clean and environment-friendly.
Description
Technical field
The present invention relates to environment-friendly type fuel, specifically a kind of environment-friendly type fuel of enzyme modified.
Background technology
Along with energy dilemma is on the rise and the continuous increase of consumption of petroleum amount, cost and the price of high-grade fuel oil escalate, and therefore and little by little people wish with reduced fuel oil replacement high-quality fuel oil.This makes various oil fuel all to heaviness future development, to improving the productive rate of this boiling range in petroleum products refining process, reaches the object of increasing output of diesel oil; And due to the heaviness of diesel oil,
Can cause the quality variation of heavy fuel oil (HFO), the problems such as firing system carbon deposit and coking or " black smoke from exhaust ", parts and components of diesel engine corrosion are more and more serious.
For improving fuel qualities to improve combustionproperty, to reduce hazardous emission, for improving the utilization ratio of petroleum products, except relying on, improve refining of petroleum level, in processed oil, add fuel dope and can change some character of fuel oil, make it to be conducive to improve combustionproperty and reduce engine emissions figure and energy-conservation object to reach.For example patent ZL99122553.8 discloses a kind of environment protection type liquid fuel, by base oil, oxygenated additive, antiknock dope, perfect combustion catalyzer, formed, oxygenated additive is comprised of polynary low-carbon alcohol and synthetic ether, antiknock dope is to be mixed by pentacarbonyl iron and diamyl iron, fuel oil additive is to be mixed by toluene, the tertiary butyl, camphor, and perfect combustion catalyzer is to be mixed by hydrogen peroxide, potassium permanganate, phenylcarbinol.Patent CN100398631C discloses a kind of environment-friendly methanol diesel oil, its be by the biofuel after modification and methyl alcohol, petrifaction diesel at normal temperatures and pressures mix and blend obtain.The environment-friendly methanol diesel oil of this patent is by first can dissolving each other with these two kinds of polar materials of methyl alcohol modification biological diesel oil the adding assistant not in the situation that to existing biofuel modification with arbitrary proportion, but while exceeding 45% due to methanol content, need to could be the normal operation that guarantees diesel engine at the environment-friendly methanol diesel oil described in this patent of application to existing diesel engine transformation, therefore, its application has been subject to certain restriction.
Except by adding fuel dope, with biodegradable, nontoxic, the biofuel completely that burns, substitute traditional fuel, can also reach the object of energy-saving and environmental protection.For example, biofuel is a kind of mineral diesel surrogate of high-quality, be typical " green energy resource ", mainly by rapeseed oil, soybean oil, recovery culinary art oil, the fat cracking of animal wet goods renewable oils or transesterification reaction, made, there is higher economic benefit, environmental benefit and social benefit.Biofuel realizes by catalytic cracking solution, ester-interchange method and ionic liquid method, and some making methods are comparatively complicated, and cost is higher.
Currently reported fuel oil additive is mainly by purification agent and frostproofer, flowing property improving agent and pour point depressant, antioxidant and corrosion inhibitor, octane enhancing additive and octane promoter, ignition dope etc.; It is several that diesel-dope mainly contains cetane value elevator, combustion improver, smoke suppressor, fluidity improver, antioxidative stabilizer, biocide etc., by adding some additives, can realize the improvement to diesel combustion performance, cetane value be can improve, oil consumption and flue gas reduced, but in additive, be mostly to use some organic solvents, there is potential safety hazard or cannot really solve the air pollution problems inherent in tail gas.As the additive that contains dimethyl formamide composition, dimethyl formamide is mainly as industrial solvent, there is pungency, it is a kind of inflammable liquid, chance naked light, Gao Re can cause combustion explosion, can even blast with the vitriol oil, nitrosonitric acid vigorous reaction, danger is higher, and dimethyl formamide still cannot really solve the air pollution problems inherent that the nitride in tail gas causes.
summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of environment-friendly fuel of enzyme modified is provided, this fuel is by biological enzyme, to carry out modification to obtain, and has that cetane value is high, sulphur content is low, ash content is low, the feature of energy-conserving and environment-protective, and its manufacture process is simple, safety, clean environment firendly.
For addressing the above problem, the technical solution adopted in the present invention is: a kind of environment-friendly type fuel of enzyme modified, by diesel oil, ethanol, Alkyl nitrate properties-correcting agent, enzyme modified agent, be mixed with and formed, the volume percent of each component is as follows: diesel oil 60-90%, ethanol 8-30%, Alkyl nitrate properties-correcting agent 0.1 ~ 1%, enzyme modified agent 1-10%.
Described enzyme modified agent is the microbial lipase that derives from yielding lipase mushroom.
Described yielding lipase bacterium is preferably black-koji mould.
Described Alkyl nitrate properties-correcting agent is one or both in 2-Nitromethane 99Min., nitro ethyl ester, nitric acid butyl ester or amyl nitrate.
The environment-friendly type fuel of enzyme modified of the present invention, its preparation process is as follows: in retort, add diesel oil, ethanol and enzyme modified agent, sealed reaction 24-48 hour, then add Alkyl nitrate properties-correcting agent to stir, react and can make for 5-10 minute.
The present invention with respect to the beneficial effect of prior art is: after Alkyl nitrate complex liquid joins in diesel oil, degeneration molecular reaction before may catching fire with fuel molecule, the elicitation procedure that has changed chain reaction, has shortened delay period, thereby has improved cetane value; Biological enzyme has efficient katalysis, and the carrying out of modified-reaction accelerated in catalysis, and biological lipase can catalyzing oil hydrolysis by using, generates lipid acid, glycerine and monoglyceride or diester, improves fuel value; Microbial lipase has the action pH wider than animals and plants lipase, operative temperature scope, high stability and activity, substrate is had to specificity, the fuel that method of the present invention obtains has that cetane value is high, sulphur content is low, ash content is low, the feature of energy-conserving and environment-protective, and its manufacture process is simple, safety, clean environment firendly.
