The invention aims to provide a high-efficiency gasoline desulfuration alcohol activating agent by aiming at the disadvantage of a gasoline alkali-free fixed bed desulfuration alcohol technology. The gasoline additive comprises the following raw materials in parts by weight: a pungent increasing agent, a catalyst, antioxygen, an antiknock agent, a cleaning agent and a solvent. According to the invention, the gasoline additive is added in an oil product in a certain ratio so that the octane numbers of low-grade naphtha and catalytic gasoline are improved to 93# and 97# from 80# and 90#; the gasoline additive is prepared at normal temperature and normal pressure and has the advantages of abundant raw material, simple technology, low cost and good anti-explosion performance; a gasoline detergent, the antioxygen and the like are added in the gasoline additive so that gasoline burning performance is improved, and carbon deposition and residual colloid generated on a gasoline engine after burning are removed; the octane number of the gasoline can be obviously improved, the octane number can be improved by 3-15 units, the anti-explosion performance of the gasoline is improved, the combustion performance of the gasoline in the gasoline engine is improved, the thermal efficiency is improved, oil consumption is lowered, power is improved, the discharge amount of harmful substances is lowered, and the service life of the gasoline engine is prolonged.
Description
Technical field
The invention belongs to chemical field.
Background technology
The burning of gasoline and pinking: during petrol motor work, gasoline and air form uniform mixed gas in the combustion chamber, influenced by pyritous, and a large amount of ROOH of RH generation also accumulates in the gasoline.Flame transmission speed is high especially when igniting; Temperature, pressure in the cylinder is raise suddenly; Transient temperature can reach 3000～4000 ℃, and pressure can rise to more than the 10MPa, and the pressure propagation frequency can reach 5000 times/s; Thereby make part of fuel have little time burning and fully just discharge cylinder, Here it is phenomenon of detonation.Phenomenon of detonation had both reduced economy, dynamic property and the thermo-efficiency of mover, had damaged engine component again and had shortened engine operational life.
The meaning of gasoline octane rating and the interpolation of additive: the gasoline trade mark adopts octane value to divide, and octane value is the most important weight indicator of motor spirit, and it has reflected the oil Refining Technologies level of a country.The petrol engine compression ratio improves, and its thermo-efficiency increases, oil consumption descends, and require octane value also to increase, and the effective and the most most economical approach of boosting of octane rating adds gasoline dope exactly in gasoline.
Patent CN1394940A relates to a kind of RONA and production technique thereof, and its feed composition is Alpha-Methyl aniline, MTBE, toluene, straight-run spirit, raffinates oil and DBPC 2,6 ditertiary butyl p cresol.The capability of antidetonance of this RONA is good, but Alpha-Methyl aniline proportion is bigger in the component, has increased the discharging of NOx in the tail gas; Environmental pollution is caused in MTBE meeting polluted underground water source, substitute this two kinds of components so need to seek new additive.
Patent CN101298573A relates to a kind of gasoline anti-knock agent, and its feed composition is methyl alcohol, MTBE and methyl cyclopentyl-dialkyl-tricarbon manganium.This gasoline anti-knock agent contains MTBE, can pollute environment.
California, USA played the forbidding MTBE in 2004, and Arizona State, the Connecticut State and New York etc. are also in forbidding MTBE in 2005.The MTBE incorporation is also reduced in other states one after another, and adds the ranks of forbidding MTBE.Australia is also in forbidding MTBE in 2004.Rose in 2006, the paces of U.S. gasoline forbidding MTBE are further accelerated.Rise in May, 2006, the U.S.'s existing 25 states forbidding MTBE.Since on May 6th, 2010, USEPA forbade with methyl alcohol being the gasoline dope of the MTBE of raw material as necessary use.
Along with Chinese economic development, the required consumption with fuel gasoline of communications and transportation is increasing; Along with people's is to the enhancing of environmental consciousness, and general leaded efficiently, ferrous metal class additive is because the PM for particulate matter that plumbous toxicity and other metal species compounds itself produces pollutes and to engine cylinder and exhaust system harm, is substituted gradually or forbids.
Summary of the invention
The objective of the invention is shortcoming, a kind of acvator of demercaptaning for gasoline efficiently is provided to above-mentioned gasoline alkali-free fixed bed doctor process existence.
The present invention is made up of the following weight parts proportion raw material:

Sanitising agent is N, N-two inferior bigcatkin willow tn 0.02 ~ 0.05
Solvent is the mixture 3.35 ~ 31.38 of toluene or YLENE or toluene and YLENE.
The preparation method of gasoline dope of the present invention,
Increase hot agent Ethyl Tertisry Butyl Ether 50 ~ 70, catalyst carbon dimethyl phthalate 18 ~ 25, oxidation inhibitor 2 by weight getting; 6-ditertbutylparacresol 0.5 ~ 1, octane promoter methyl cyclopentyl-dialkyl-tricarbon manganium 0.1 ~ 0.6, sanitising agent N, the inferior bigcatkin willow tn of N-two 0.02 ~ 0.05, solvent toluene, YLENE or the two mixture 3.35 ~ 31.38; At normal temperatures and pressures, each raw material is added in the reaction kettle successively, stirred 20 ~ 30 minutes, thorough mixing is even, leaves standstill 30 minutes again, can make gasoline dope of the present invention; Answer lucifuge in the production process.
The addition of gasoline dope of the present invention in gasoline is 0.5 ~ 6% (m/m).
The present invention adds certain proportion in oil product, the octane value that can make low grade petroleum naphtha, catalytic gasoline is by 80#, and 90# brings up to 93#, 97#.Preparation at normal temperatures and pressures, abundant raw material, technology is simple, and cost is low.The capability of antidetonance is good, also is added with gasolene cleaner, oxidation inhibitor etc., can improve the combustionproperty of gasoline, carbon distribution and the residual colloid that removing burning back produces on petrol motor.Can significantly improve the octane value of gasoline, octane value can improve 3 ~ 15 units, improves the gasoline capability of antidetonance; Improve the combustionproperty of gasoline in petrol motor, improve thermo-efficiency, reduce oil consumption; Improve power, reduce the discharge of poisonous waste amount, prolong the work-ing life of petrol motor.The hot agent that increases in the gasoline dope of the present invention uses Ethyl Tertisry Butyl Ether to substitute MTBE; Has lot of advantages; Ethyl Tertisry Butyl Ether is improved except the octane value that can make gasoline; Can also use as cosolvent, make the economy of gasoline and security all good than the gasoline that adds MTBE; The boiling point of Ethyl Tertisry Butyl Ether is higher, mixes not generating azeotropic compound mutually with hydro carbons, so both can reduce in-engine vapour lock, can reduce vaporization losses again; Ethyl Tertisry Butyl Ether is water-soluble little than MTBE, and is easy to microbiological degradation, and than MTBE environmental protection, so it has very big market potential.
