AROMATIC HYDROCARBONS ALKYLATION AND LIQUID-SOLID CIRCULATING FLUIDIZED BED FOR ALKYLATION

摘要

A continuous catalytic alkylation process for aromatic hydrocarbons of their derivates with solid acid catalyst, which employs a liquid-solid circulating fluidized bed involving six main means consisting of liquid-solid cocurrent riser reactor, settling washing tower for spent catalyst, liquid-solid cocurrent riser regenerator, settling washing tower for regenerated catalyst and two liquid-solid cyclonic separators, the continuous reaction-regeneration process is effected.
