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 investigated. The effect of temperature is also studied. The two-channel model is shown to provide a practical way to predict the effects of the various operating conditions on the performance of the LSCFB reactor and to be helpful for the design of the LSCFB reactors.
