Description
Technical field
The invention belongs in the method that has refining hydrocarbon ils under the situation of hydrogen, more particularly, is to belong to a kind of method that reduces gasoline fraction sulphur, olefin(e) centent.
Background technology
Along with the continuous enhancing of people to environmental consciousness, the discharging of hazardous and noxious substances will be strictly controlled in the vehicle exhaust, and therefore the oil quality as motor spirit requires more and more tighter.For this reason, various countries have all proposed very harsh restriction index to motor spirit specification such as oxygen level, vapour pressure, benzene content, aromatic hydrocarbons total content, boiling point, olefin(e) centent and sulphur content etc., to reduce emission of harmful substances.Contrast China motor spirit new standard can find that the subject matter of China's quality of gasoline is sulphur content and olefin(e) centent height.The major cause of sulfur in gasoline and olefin(e) centent superelevation is because the ratio of catalytic cracking (FCC) gasoline in gasoline pool is too high.In China, FCC gasoline is main blend component in the gasoline mediation pond, accounts for more than 80%.FCC content of sulfur in gasoline height, olefin(e) centent height, and the raw material of processing along with FCC develops to the heaviness direction, will cause sulphur content and olefin(e) centent in the FCC gasoline further to increase.Therefore reduce FCC sulfur in gasoline and olefin(e) centent and be the main path of sulphur and olefin(e) centent in the control motor spirit.
US5399258 discloses a kind of method of handling heavy FCC gasoline.First section through hydrogenation desulfurization and denitrogenation, hydrogenation of olefins saturated after, it is two anti-that the intermediate product that obtains directly enters, and carries out the octane value recovering reaction.One anti-temperature of reaction is 347～410 ℃, maintains an equal level with two anti-temperature of reaction.Because an anti-temperature of reaction is too high, causes final product to produce a large amount of mercaptan sulfurs, temperature is high more, and the amount of the mercaptan sulfur of generation is big more.
US6184176 discloses a kind of sorbent material production method that is used to handle FCC gasoline, and the sorbent material of producing with this method carries out adsorption desulfurize to FCC gasoline, sulfur in gasoline can be reduced to very low-level, but olefin(e) centent does not almost reduce.
WO98/53030 discloses a kind of method of the FCC of processing gasoline.First section is carried out reactions such as cracking, aromizing, alkylation with catalytically cracked gasoline under an acidic catalyst effect, then intermediate product is entered second section and carry out reactions such as hydrogenating desulfurization, denitrogenation, alkene be saturated under the Hydrobon catalyst effect.Because the aromatization of alkene and naphthenic hydrocarbon and the alkylating of aromatic hydrocarbons and alkene make that aromaticity content increases in the product.
CN1316485A discloses a kind of gasoline modified method.First section is carried out olefin isomerization, carries out olefin hydrogenation at second section then.First section dress be olefin isomerization catalyst, second section dress be olefin hydrogenation catalyst.This patent is only carried out olefin isomerization for first section, simultaneously other impurity such as sulphur is not proposed treatment process.
Summary of the invention
The purpose of present technique invention is exactly on the basis of existing technology, proposes a kind of method that reduces gasoline sulfur, olefin(e) centent simultaneously, to produce all premiums of satisfied " world's fuel oil standard " III class gasoline index specification of sulphur, olefin(e) centent.
Method provided by the invention comprises:
(1), gasoline stocks, hydrogen contact with hydroisomerization catalyst, carries out that hydrogenating desulfurization, alkene are saturated, olefin isomerization, cracking of olefins reaction, separates hydrogenated oil and obtain lighter hydrocarbons and gasoline fraction, hydrogen-rich gas recycles;
(2), the described gasoline fraction of step (1) contacts with adsorptive catalyst, carries out obtaining behind the adsorption desulfurize gasoline products of low-sulfur, olefin(e) centent.
The present invention produces the premium that sulphur, olefin(e) centent all satisfy " world's fuel oil standard " III class gasoline index specification, guarantees the loss of octane number minimum of gasoline simultaneously.
