Abstract
The present invention discloses a series of a fuel combustion improving agent for diesel engine fuel, which is used for petroleum refining and an engine oil tank. According to different purposes, the improving agent can be prepared into uniform and transparent oil-soluble liquid by nitric acid ester substances of primary alcohol and secondary alcohol of C3 to 12 and a corresponding compounding agent according to the given proportion and condition, wherein the corresponding compounding agent can be prepared from aromatic hydrocarbon dioxide, aromatic halogenated hydrocarbon, polycyclic aromatic hydrocarbon halide, etc. When the improving agent is applied to diesel oil lower than cetane number in an oil refinery, the cetane number can be substantially increased, and the production capacity of the commercial diesel oil is increased. Simultaneously, the usability in an engine can be improved. The improving agent can reduce the explosion pressure of a cylinder, the harmful discharge and the oil consumption and improve the cold-starting performance when directly applied to the engine oil tank.
Description
The invention belongs to the improving agent that improves the diesel-fuel combustionproperty.
Produce high-octane lead-less gasoline, will cause the increase of the catalytic cracking diesel oil amount of medium fraction.Effectively utilizing this part fraction increases commercial Dissel oil output, also will cause containing in the diesel oil increase of catalytic cracking diesel oil component, the reduction of 16 alkane values, thus make poor, the starting difficulty of engine ignition.
The simple 16 alkane values that improve fuel make it to reach specification requirement, also far can not solve to contain to urge the more low-grade diesel oil of bavin to use problem.The cracking component is many in the diesel oil, aromatic hydrocarbons is many, can make that carbonizing of engine is many, smoke evacuation is dense, wearing and tearing are big, particularly will reduce the noxious emission of engine, and the fuel oil consumption more needs a kind of fuel dope of comprehensive function.Combustion improving agent of the present invention is a kind ofly to improve the catching fire of diesel engine, startability, and the multifunctional series additive of combustion processes.
Before the present invention, the fuel combustion improving agent roughly has three types.
1. combustion improving agent:
Previous patent, the described improving agent of document or ignition dope are mainly used in low reduced fuel oil, are used for catalysis combustion combustion processes, improve the fuel feed atomizing, removing carbon, charcoal cigarette etc.How to form by oil soluble organic metal salt, various oleophylic, hydrophilic surfactant active.The nearest lightweight oil combustion improving agent that occurs, what have contains organic metallic compound, has wear and tear in machines, secondary pollution problems, though that the not containing metal that has adds dosage is big, function is few, is unsuitable for containing the low-grade diesel oil of low hexadecane value of catalytic diesel oil.
