Abstract
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.

A catalyst comprising as first cracking component a zeolite beta having a silica to alumina molar ratio of at least 50 which is in the form of crystals with sizes in the range from 20 to 95 nm, a second cracking component selected from the group consisting of (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.
A process for converting a hydrocarbonaceous feedstock into lower boiling materials which comprises contacting the feedstock with hydrogen at elevated temperature and elevated pressure in the presence of a catalyst composition comprising as first cracking component a zeolite beta having a silica to alumina molar ratio of at least 50 which is in the form of crystals with sizes in the range of 20 to 95 nm;
- a second cracking component selected from the group consisting of (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.
