Abstract
A process for catalytic cracking using a catalyst obtained by preparing pillared interlayered clay materials comprises the steps of contacting a smectite containing material, preferably bentonite, with a solution comprising at least one of ammonium and alkali metal carboxylates and alkali metal carbonates and bicarbonates, plus preferably also alkali metal dithionite; separating the thus-contacted material from the solution; treating the separated material with a solution comprising a polymeric cationic hydroxy metal complex, preferably of aluminum (more preferably, polymeric hydroxy aluminum chloride); separating and finally heating the thus-treated smectite material. The pillared interlayered clay material of this invention can be intimately admixed with zeolite. The pillared interlayered clay material of this invention, with or without zeolite, can be used as catalyst for cracking hydrocarbon-containing oils.
