Dearomatization of Motor Fuels by Alkylation Over Zeolite Catalysts

Аннотация

A study was carried out on gasoline dearomatization in the presence of zeolites and subsequent ractionation of the alkylate to give dearomatized gasoline and an aromatic hydrocarbon concentrate. Catalyst acid sites were shown to play a part in the alkylation reactions. In the case of a feedstock with 1:1 aromatic hydrocarbon:styrene weight ratio, the aromatic hydrocarbon content in the gasoline was reduced from 22.58 to 6.51% upon complete styrene conversion. As a result, the gasoline component was environmentally friendly and phenylarylethane products suitable for use as dielectric liquids were obtained.
