Abstract
Cracking catalysts which yield higher octane gasoline than conventional cracking catalysts are made with large pore size zeolites such as zeolite Beta and zeolite ZSM-20 in the low sodium, H.sup.+ form. These zeolites are mixed with a matrix which contains at least a binder and formed into catalyst particles. These catalysts are especially suitable to be used in fluid catalytic cracking.
Claims10
A catalytic cracking catalyst comprising a primary, large pore high silica zeolite exchanged to a low soda level which is mixed in a matrix, said primary large pore zeolite being present in a catalytically effective amount for catalytic cracking and in an amount up to 80% by weight of the total mixture and where said primary large pore zeolite is not a Y-faujasite nor an X-faujasite.
