  • Process and apparatus for preparation of ethylbenzene by alkylation of benzene with dilute ethylene contained in dry gas by catalytic distillation
    Patent number: 6504071
    Abstract: A new process for the preparation of ethylbenzene by alkylation of benzene with dilute ethylene contained in dry gas by catalytic distillation and the apparatus used therefor are disclosed. The new process includes the pretreatment of raw refinery dry gas, the gas-liquid-solid three phases alkylation of benzene with the ethylene over a solid catalyst in a catalytic distillation tower, and concurring course of distillation separation of product mixture. The performance, type, and loading way of catalyst and distillation packing should satisfy the given requirements. The invention has many advantages such as simple apparatus structure and ease in operation, moderate operation conditions, large catalyst capacity, high product quality, long catalyst lifetime, etc.
