    • A process for alkylating aromatic compounds wherein the product aromatics are provided with one or more alkyl groups possessing at least two carbon atoms is disclosed wherein starting aromatic compound(s) and an alkylating atent which is a mixture of hydrogen and/or a hydrogen-containing substance which provides hydrogen under process conditions and a carbon oxide, e.g., a mixture of syngas (hydrogen and carbon monoxide) are reacted at elevated temperature in the presence of an activated catalyst containing metal values selected from the group consisting of iron, cobalt, ruthenium, manganese, rhodium and osmium, and a zeolite having a constraint index of 12 or less, e.g., ZSM-5. The alkylated aromatics can be dealkylated by known and conventional means to provide olefin and the dealkylated aromatics can be recycled to the alkylation zone.
    • 公开了一种芳族化合物的烷基化方法,其中产物芳族化合物具有一个或多个具有至少两个碳原子的烷基,其中起始芳族化合物和烷基化剂是氢和/或含氢的混合物 在工艺条件下提供氢的物质和碳氧化物,例如合成气(氢气和一氧化碳)的混合物在升高的温度下在活性催化剂存在下反应,所述催化剂含有选自铁,钴,钌的金属值 ,锰,铑和锇以及具有12或更小约束指数的沸石,例如ZSM-5。 烷基化芳族化合物可以通过已知和常规方法脱烷基化以提供烯烃,并且脱烷基化的芳族化合物可以再循环到烷基化区。
