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 3000C 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 4000C 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： 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 4000C 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.
