ABSTRACT:
A hydrocarbon conversion crystalline catalyst composition is described comprising 5 to 90% by weight of a crystalline aluminosilicate zeolite, 5 to 90% by weight of a porous inorganic oxide, 1 to 20% by weight of a Group VI metal component (calculated as the corresponding oxide), 0 to 7% by weight of a Group VIII metal component (calculated as the corresponding oxide), and at least one of phosphorus and boron components. The weight ratio of the amount of the phosphorus+boron components (calculated as elemental phosphorus and elemental boron) to the Group VI metal component (calculated as the corresponding oxide) is from 0.01:1 to 0.08:1 and the weight ratio of each of phosphorus and boron to the Group VI metal component is below 0.045:1. This composition is prepared by contacting a support comprising the crystalline aluminosilicate zeolite and inorganic oxide with a solution containing a Group VI metal component and at least one phosphorus or boron component. The weight ratio of elemental phosphorus+elemental boron to the Group VI metal component (calculated as the corresponding oxide) is from 0.01:1 to 0.08:1 and the weight ratio of each of elemental phosphorus and elemental boron to the Group VI metal component (also calculated as the corresponding oxide) is below 0.045:1. The solution has a pH of from 3.3 to 6.0. The Group VI metal component and at least one of the phosphourus and boron components are deposited on the support.
