Process for the production of aromatic hydrocarbons

摘要

A process for the production of aromatic hydrocarbons which process comprises contacting at elevated temperature and in the vapor phase a C2 to C12 aliphatic hydrocarbon feedstock with a catalyst comprising a crystalline aluminosilicate having a silica to alumina molar ratio greater than 12:1 which has been modified by incorporation therein of aluminium either by exchange or impregnation.
