    • A method of continuously promoting the activity of solid strong acid catalysts used in acid catalyzed reactions by adding or generating water in the reaction mixture has been developed. The solid strong acid catalyst may be a sulfated metal oxide, a tungstated metal oxide, or a molybdated metal oxide. The metal oxides are oxides, hydroxides, oxyhydroxides, or oxide-hydrates of Group IV-A, Group III-A, Group III-B, and Group V-A metals. The catalyst may also contain a Group VIII metal, or when the metal oxide is a hydroxide, oxide, oxyhydroxide, or oxide-hydrate of the Group IV-A, Group III-A, or Group III-B metals, the catalyst may also contain an oxide, hydroxide, oxyhydroxide or oxide-hydrate of a Group V-A, Group V-B, Group VI-B, or Group VII-B metal as a promoter. The acid catalyzed reactions where the activity promotion method may be applied include catalytic cracking, catalytic reforming, hydrodesulfurization, isomerization, alkylation of aliphatic and aromatic hydrocarbons, polymerization, and oligomerization. The amount of water added to or generated in the reaction mixture may be from about 0.1 ppm to about 500 ppm water.
    • 已经开发了通过在反应混合物中加入或产生水来连续促进用于酸催化反应的固体强酸催化剂活性的方法。 固体强酸催化剂可以是硫酸化金属氧化物,钨酸盐金属氧化物或钼酸盐金属氧化物。 金属氧化物是IV-A族,III-A族,III-B族和V-A族金属的氧化物,氢氧化物,羟基氧化物或氧化物 - 水合物。 催化剂还可以含有VIII族金属,或者当金属氧化物是IV-A族,III-A族或III-B族金属的氢氧化物,氧化物,羟基氧化物或氧化物水合物时,催化剂也可以 含有VA族,VB族,VI-B族或VII-B族金属的氧化物,氢氧化物,羟基氧化物或氧化物水合物作为促进剂。 可以应用活性促进方法的酸催化反应包括催化裂化,催化重整,加氢脱硫,异构化,脂族和芳烃的烷基化,聚合和低聚。 在反应混合物中加入或产生的水的量可以是约0.1ppm至约500ppm的水。
