    摘要: Prevention of detrimental effects of metals such as nickel, vanadium and iron on the activity of cracking catalysts is achieved by contacting the cracking catalyst with manganese selenide. The modifying treatment of the catalyst with manganese selenide increases octane rating of the gasoline produced.

    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 and iron in the cracking catalyst are precluded or mitigated by contacting the cracking catalyst with at least one treating agent selected from the group consisting of elemental tellurium, oxides of tellurium and compounds convertible to elemental tellurium or oxide thereof during cracking or catalyst regeneration, whereby to said cracking catalyst is added a modifying amount of said treating agent.
