CATALYST COMPOSITIONS AND THEIR USE IN HYDROCARBON CONVERSION PROCESSES.

摘要

The present invention provides a catalyst composition, and a hydrocarbon conversion process in which it is used, comprising as first cracking component a zeolite beta having a silica to alumina molar ratio of at least (20) which is in the form of crystals less than 100 nm in size; a second cracking component selected from (i) crystalline molecular sieves having pores with diameters greater than 0.6 nm, (ii) crystalline, mesoporous aluminosilicates having pores with diameters of at least 1.3 nm, and (iii) clays; and at least one hydrogenation component.
