KATALYSATORZUSAMMENSETZUNG, VERFAHREN ZUM CRACKEN VON NICHT-AROMATISCHEN KOHLENWASSERSTOFFEN UND VERFAHREN ZUR IONISIERUNG VON C-8-AROMATISCHEN KOHLENWASSERSTOFFEN.

摘要

A catalyst composition consisting essentially of (a) a crystalline aluminosilicate zeolite having a silica/alumina mole ratio of at least 10 (component A) in which at least 50 % of its cationic sites are occupied by alkaline earth metal cations, (b) a refractory inorganic oxide having platinum and tin supported thereon (component B) and (c) indium (component C), the indium being supported on the zeolite in component A and/or the refractory inorganic oxide in component (B). A process for decomposing non-aromatic hydrocarbons in the presence of the catalyst composition, and a process for isomerizing C8-aromatic hydrocarbon, particularly xylenes, in the presence of the catalyst composition.
