Catalytic cracking catalysts using silicoaluminophosphate molecular sieves

摘要

Cracking catalysts containing silicoaluminophosphate molecular sieves are disclosed. Such catalysts are derived from specific silicoaluminophosphate molecular sieves of U.S. Pat. No. 4,440,871. The catalyst when used for the conversion of hydrocarbons provide product mixtures different from those obtained by use of aluminosilicates based catalysts.
