Abstract: The circulating moving bed is an innovative coupled reactor for synthesizing linear alkylbenzenes, and it only requires relatively shorter lifespan of catalyst than that of traditional fixed bed reactors. In the circulating moving bed reactor, the reaction process and the regeneration process are coupled to realize a continuous operation. As a result, the equipment investment and the operating costs can be significantly reduced. In this model, the effect of catalyst deactivation on the reaction is simulated by using the infinitesimal balance equations.The results of step changes between steady states and unsteady states are also calculated with the model.
