    摘要: Methods for preparing phosphorus containing catalysts comprising a large-pore zeolite, e.g., zeolite Beta, zeolite ZSM-12, or zeolite ZSM-20, and a matrix which have improved attrition resistance. The present invention includes the catalyst compositions produced by the above methods. Also included in the present invention are methods for the use of catalysts prepared by the present method in hydrocarbon cracking processes. It is desired to develop cracking catalysts for organic compound conversion that have improved cracking yields and have good attrition resistance. This invention involves the use of large pore siliceous zeolites and a highly siliceous matrix to produce a cracking catalyst with improved cracking yields and good attrition resistance. The invention further involves the use of phosphorus and the use of selected sequences for combining the compounds in the manufacture of the catalyst to enhance the attrition resistance of the catalyst.

    摘要: Akylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream may then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a large pore molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.
