    • A process for the manufacture of cumene by hydrogenating alphamethylstyrene with hydrogen in the presence of an alkalinated nickel aluminum oxide carrier catalyst, the improvement comprising, carrying out the hydrogenation at temperatures of about 60*- 160*C in the presence of a catalyst where the carrier material contains kappa and/or delta aluminum oxide having an alkali content of 0.1 - 5 percent by wweight of alkali oxide, wherein (if appropriate) molded aluminum hydroxide containing alkali is dried in a known manner, then it is heated in an air stream at about 400*- 500*C and thereafter steam treated at about 700*- 800*C. The calcined catalyst is then impregnated with a nickel salt in a conventional manner, the salt subsequently being completely decomposed into nickel oxide and volatile components, the nickel content of the catalyst (computed as nickel metal) being about 5 - 12 percent by weight referred to the calcined catalyst. The impregnated catalyst is thereupon reduced in a conventional manner.
    • 一种通过在碱式化的氧化铝载体催化剂的存在下用氢气氢化α-甲基苯乙烯来制造枯烯的方法,其改进包括在约60-160℃的温度下在催化剂存在下进行氢化 其中载体材料含有碱含量为0.1-5%(重量)碱性氧化物的κ和/或δ-氧化铝,其中(如果合适的话)含有碱的模制氢氧化铝以已知方式干燥,然后在 空气流在约400-500℃,然后在约700-800℃下进行蒸汽处理。然后以常规方式用镍盐浸渍煅烧的催化剂,随后将其完全分解成氧化镍和挥发性组分 ,催化剂的镍含量(以镍金属计算)为煅烧催化剂的约5-12重量%。 随后以常规方式减少浸渍的催化剂。
