PROCESS FOR THE PREPARATION OF AN AROMATIC HYDROCARBON MIXTURE

摘要

PROCESS FOR THE PREPARATION OF AN AROMATIC HYDROCARBON MIXTURE C2-C4 paraffins are converted into aromatic gasoline over a catalyst composition comprising gallium supported on a carrier and a crystalline metal silicate with a special crystal structure, which composition has been subjected once or several times to a two-stage treatment comprising reduction at a temperature of 400-650.degree.C and oxidation at a temperature of 350-700.degree.C.
