Description

Vehicle and ship additive applied to coal-based biofuel and preparation method thereof
Technical Field
The invention belongs to the technical field of vehicle fuel additives, and particularly relates to a vehicle and ship additive applied to coal-based biofuel and a preparation method thereof.
Background
Because the ignition performance, the wear resistance, the low-temperature performance and the like of the fuel of a fuel engine have strict requirements, and the coal-made fuel oil generally has the characteristics of low cetane number, poor lubricity, high condensation point and poor detergent dispersibility, and an anti-wear agent, a cetane number improver, a pour point depressant, a detergent, an antioxidant and the like are added for blending according to needs. In order to meet the requirements of good service performance and environmental protection of the fuel, the additive is used for different types of fuel, the service performance of the fuel can be improved and the exhaust pollutant emission can be improved under the condition of not changing the property of the fuel, and the promotion effect on the popularization of clean fuel is great.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a vehicle and ship additive applied to coal-based biofuel and a preparation method thereof. The invention selects related raw materials for compounding in consideration of the aspects of detergent dispersion, acid value, lubricity, cetane number, oxidation resistance, condensation point, tail gas detergency and the like, and meets the requirements of coal fuel oil on detergent dispersion, acid value, lubricity, cetane number, oxidation resistance, condensation point and tail gas detergency.
The technical scheme provided by the invention is as follows:
the vehicle and ship additive applied to the coal-based biofuel comprises the following components in parts by weight: 1-2 parts of mono-butylene succinimide, 15-20 parts of dicyclohexylamine, 15-20 parts of methyl oleate, 20-30 parts of isooctyl nitrate, 1-3 parts of di-tert-butyl-p-cresol, 1-5 parts of poly-alpha-olefin and 40-60 parts of polymethoxy dimethyl ether.
In the above technical scheme:
the method selects the mono-butylene succinimide as the detergent dispersant. As environmental regulations become more stringent and the emission requirements for pollutants from the exhaust gas of vehicles increase, the development of ashless detergents has become a necessary trend. Most ashless detergent dispersants are small molecular amine compounds and oligoamine compounds. Wherein the small molecular amine detergent comprises mono-succinimide, bis-succinimide, N-phenylstearamide and the like, and the oligomer amine comprises alkyl aminated, polyether amine, Mannich reaction products and the like;
dicyclohexylamine is selected as an alkali value retention agent to prevent the fuel acid value from being too high;
methyl oleate is selected as a lubricant. The fatty acid ester antiwear agent is a fuel antiwear agent which is most applied at present and is prepared by reacting long-chain unsaturated fatty acid with alcohol. The material does not contain heteroatoms except oxygen, does not increase the emission of tail gas pollutants, has better polarity due to the oxygen atom, can be adsorbed on the friction surface to form a protective film, and plays a better lubricating role;
isooctyl nitrate is selected as the cetane number improver. The cetane number is an important index for measuring the ignition performance and the anti-explosion performance of the fuel, and the cetane number has important influence on the emission of harmful substances of the fuel, the starting performance, the fuel consumption and the like. When using fuels with a high cetane number, the emissions of harmful substances are considerably less than in fuels with a low cetane number. If the cetane number is too low, knocking occurs when the vehicle starts and runs, and the engine is damaged, so that the fuel consumption is increased. Nitrate series cetane number improver is a type of improver which is widely applied at present, the production cost is low, and the effect of improving the cetane number of fuel is obvious when the additive amount is less;
di-tert-butyl-p-cresol is used as an antioxidant, so that the problems of easy color change, oxidation and the like of coal-based fuel oil are solved;
polyalphaolefin is selected as a pour point depressant, so that the condensation point of coal-based fuel oil is reduced, and the application area of the fuel oil is increased;
the polymethyl dimethyl ether is selected as a tail gas cleaning agent, can be used as a blending component of a clean fuel, has similar physical properties to the fuel, and is used in blending the fuel without modifying an oil supply system of a vehicle engine. The cetane number is up to 76, the oxygen content is 47-50%, no sulfur and no aromatic hydrocarbon exist, the cold filter plugging point of the fuel can be obviously reduced, the combustion quality of the fuel in an engine is improved, and the heat efficiency is improved, so that the emission of fuel oil is improved, and the tail gas detergency is improved.
The invention also provides a preparation method of the additive for the vehicle and the ship, which is applied to the coal-based biofuel, and the preparation method comprises the following steps: according to the weight parts, 1-2 parts of mono-butylene succinimide, 15-20 parts of dicyclohexylamine, 15-20 parts of methyl oleate, 20-30 parts of isooctyl nitrate, 1-3 parts of di-tert-butyl-p-cresol, 1-5 parts of poly-alpha olefin and 40-60 parts of polymethoxy dimethyl ether are added into a reaction kettle, stirred at normal temperature for 4-6min, filtered by a 350-plus 450-mesh plate frame filter, and the filtrate is taken, namely the additive for vehicles and ships applied to the coal-based biofuel. Preferably, the filtration is carried out by a 400-mesh plate frame filter.
In general, the additive for vehicles and ships applied to the coal-based biofuel provided by the invention can be used for remarkably improving the cleaning dispersibility, the oxygen resistance and the corrosion resistance of the fuel, reducing the condensation point of the fuel, improving the cetane number of the fuel and improving the cleaning property of tail gas discharged by the fuel. Five thousandths of the total weight is added, and the performance is comprehensively improved by 5-10%.
