Problems solved by technology

[0008] When the above technology is used to increase the octane number of naphtha, the naphtha raw material often needs to be pretreated, and the fractions are divided into different fractions for separate treatment. Moreover, the prior art mostly uses precious metal catalysts to hydrogenate light distillates. Structural treatment, hydrocracking or catalytic reforming treatment of heavy distillate, has the disadvantages of complicated process and high energy consumption

Abstract

The invention provides an environment-friendly process for producing motor gasoline from naphtha, which belongs to the technical field of coal chemical industry. C 4‑ Component, C 5 / C 6 components and C 7+ component, where C 5 / C 6 Components undergo hydroisomerization reaction to obtain isoparaffin oil, C 7+ The components are reformed to obtain aromatic oil, and the C 4‑ After components, isoparaffin oil and aromatic oil are mixed evenly, motor gasoline is obtained. The present invention is an environmentally friendly process for producing ultra-low-sulfur, olefin-free, high-octane clean motor gasoline, which has the advantages of simple method, mild reaction conditions, low cost, and can significantly increase the octane value of motor gasoline, and has wide applications. prospect.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to an environmentally friendly process for producing motor gasoline from naphtha. Background technique [0002] Clean fuel production has always been one of the main tasks of refiners. However, with the shortage of oil resources and rising crude oil prices, how to use limited resources to maximize the production of products required by the market is a challenge for oil refiners. The main components in the gasoline pool are catalytically cracked gasoline, catalytically reformed gasoline, alkylated gasoline and C 5 / C 6 Isomerized gasoline. Except for catalytic cracking gasoline, which is obtained from heavier raw materials, the others are obtained by converting naphtha or light hydrocarbons. [0003] Coal-to-naphtha is divided into direct coal liquefaction naphtha and coal indirect liquefaction naphtha. Since a large number of mono- and di-olefins are produced dur...
