    摘要: 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.

    摘要: A novel cracking catalyst, a method of preparing same and an improved hydrocarbon cracking process are provided wherein adverse effects of metals such as nickel, vanadium, iron, copper and cobalt in the cracking catalyst are precluded or mitigated by contacting the cracking catalyst with (A) at least one of elemental antimony and compounds thereof and (B) at least one of element tin and compounds thereof whereby there is added to said catalyst a modifying amount of each of (A) and (B) with the weight ratio of antimony to tin being such as to provide passivation of the contaminating metals greater than the sum of the passivation effects of each of (A) and (B) individually. In general the ratio will be in the range of from 0.001:1 to 1000:1, and preferably will be in the range of 0.05:1 to 50:1.
