摘要： A method of treating a ZSM-5-type zeolite catalyst is carried out by treating a ZSM-5 zeolite catalyst having a silica/alumina mole ratio of at least about 200 with a phosphorus compound. The phosphorus-treated ZSM-5 zeolite catalyst is calcined and steamed. Steaming of the catalyst is carried out at a temperature of less than about 300° C. The phosphorus-treated ZSM-5 zeolite catalyst has less than 0.05% by weight of the catalyst of any other element other than phosphorus provided from any treatment of the ZSM-5 zeolite with a compound containing said other element. The catalyst may be used in aromatic alkylation by contacting the catalyst with feed of an aromatic hydrocarbon and an alkylating agent within a reactor under reactor conditions suitable for aromatic alkylation. Water cofeed may be introduced water into the reactor during the aromatic alkylation reaction.

摘要： Disclosed is a bound phosphorus-modified zeolite catalyst. Zeolite is treated with a phosphorus compound to form the phosphorus-treated zeolite. Binder material is treated with a mineral acid prior to being bound with the phosphorus-modified zeolite. The binder material includes inorganic oxide materials, such as alumina, clay, aluminum phosphate and silica-alumina, in particular, a binder of alumina or clay or their combinations. The mineral acid includes hydrochloric acid, nitric acid, phosphoric acid or sulfuric acid. The phosphorus-treated zeolite is combined with the acid-treated inorganic oxide binder material to form a zeolite-binder mixture. Water is added to form an extrudable paste which maybe shaped and is heated to a temperature of about 400° C. or higher to form a bound phosphorus-modified zeolite catalyst. For aromatic alkylation, the bound phosphorus-modified zeolite catalyst is contacted with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.

摘要： A zeolite catalyst is prepared by treating a zeolite with a phosphorus compound to form a phosphorus-treated zeolite. The phosphorus-treated zeolite is heated to a temperature of about 300° C. or higher and combined with an inorganic oxide binder material to form a zeolite-binder mixture. The zeolite-binder mixture is heated to a temperature of about 400° C. or higher to form a bound zeolite catalyst. The bound zeolite may exhibit at least two 31P MAS NMR peaks with maxima at from about 0 to about −55 ppm, with at least one peak having a maximum at from about −40 to about −50 ppm. Zeolites containing 10-oxygen ring pores that have been prepared in such a way may be used in aromatic alkylation by contacting the bound zeolite catalyst with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.

摘要： A method of modifying a zeolite catalyst to increase para-xylene selectivity of the zeolite catalyst in toluene methylation reactions is provided. The method includes forming a slurry of a ZSM-5-type zeolite and an aqueous solution of a phosphorus compound. Water is removed from the slurry to provide a non-steamed, phosphorus treated ZSM-5 zeolite catalyst without deposition of phosphorus onto the catalyst by organophosphorus vapor deposition. The resulting non-steamed, phosphorus treated ZSM-5 zeolite catalyst has a pore volume of from 0.2 ml/g or less and provides greater than 80% para-xylene selectivity of mixed xylenes when used in toluene methylation.

摘要： A catalyst for use in aromatic alkylation, such as toluene alkylation with methanol, is comprised of a zeolite with pore size from about 5.0 to about 7.0 Å containing a hydrogenating metal. The catalyst may be used in preparing an alkyl aromatic product by providing the catalyst within a reactor. The catalyst may be contacted with an aromatic hydrocarbon and an alkylating agent in the presence of hydrogen under reaction conditions suitable for aromatic alkylation. The catalyst may also be treated to further increase its stability. This is accomplished by heating the hydrogenating metal loaded zeolite catalyst in the presence of a reducing agent prior to use in an aromatic alkylation reaction to a temperature of from about 400° C. to about 500° C. for about 0.5 to about 10 hours.
