Method for preparing alkylate oil by catalysis of gallium chloride acid ion solution

Abstract

The invention relates to a method for preparing alkylate oil by catalyzing iso-butane and butylenes preparation by a modified gallium chloride acid ion solution in the field of petrochemical industries. The catalyst has higher activity, selectivity and stability in the alkylation process, so that the alkylate oil prepared by the catalyst is characterized in that the quality and the yield are good and high, the catalyst and the alkylation product are easy to separate, the operation is simple and convenient, the corrosion is small, few side product is generated, and little environment pollution is caused.

Description

Technical field: [0001] The invention belongs to the field of petrochemical industry, and mainly relates to a preparation method of an ionic liquid alkylation catalyst, specifically refers to a method for producing high-octane gasoline by using trifluoroethanol or metal chloride-modified chlorogallate ionic liquid as a catalyst . Background technique: [0002] The strong acid-catalyzed C4 alkylation process began in the 1930s and is an important process for the production of clean gasoline in the petrochemical field. It has become an ideal gasoline blending component and is known as the "golden liquid" in the oil refining industry. [0003] At present, the industrial production of alkylation processes mainly includes sulfuric acid and hydrofluoric acid processes. The process technology is relatively mature, but the two processes have high energy consumption and large pollution, and there are many hidden dangers, which limit their wide application. The sulfuric acid alkylat...
