    • 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.
    • 公开了结合的磷改性沸石催化剂。 用磷化合物处理沸石以形成磷处理的沸石。 在与磷改性沸石结合之前,用无机酸处理粘合剂材料。 粘合剂材料包括无机氧化物材料,例如氧化铝,粘土,磷酸铝和二氧化硅 - 氧化铝,特别是氧化铝或粘土的粘合剂或它们的组合。 无机酸包括盐酸,硝酸,磷酸或硫酸。 磷处理的沸石与酸处理的无机氧化物粘合剂材料组合以形成沸石 - 粘合剂混合物。 加入水以形成可挤出的糊料,其可成形并加热至约400℃或更高的温度以形成结合的磷改性的沸石催化剂。 对于芳族烷基化,结合的磷改性的沸石催化剂在适于芳族烷基化的反应条件下与芳族化合物和烷基化剂的芳族烷基化进料接触。

    • 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 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.
