HYDROCARBON CRACKING CATALYSTS WITH PROMOTER MIXTURES

摘要

HYDROCARBON CRACKING CATALYSTS WITH PROMOTER MIXTURES A mixture of rare earth hydrogen Y type zeolite, and hydrogen ferrierite is used as a catalyst for the conversion of hydrocarbons. The rare earth hydrogen Y and a hydrogen ferrierite mixture may be advantageously combined with amorphous matrix components such as silica, alumina, silica-alumina hydrogel and/or clay to form cracking catalyst compositions of the fluid or moving bed type.
