Effect of radial flow nonuniformity on the alkylation reaction in a liquid-solid circulating fluidized bed (LSCFB) reactor

摘要

A two-channel reaction model is proposed for reactions in the liquid-solid circulating fluidized bed (LSCFB). With the two-channel flow model, the kinetics of benzene alkylation with dodecene over zeolite HY catalyst, and the deactivation kinetics of the catalyst, the effects of the various operating parameters on the radial distributions of the reactant concentration and the catalyst activity and on the reaction conversion in the liquid-solid riser reactor are invstigated.
