Fixed bed reactors are widely used in desulfurization processes. However, this kind of reactors has an obvious disadvantage leading to discontinuous operation that the catalysts and adsorbents must be regenerated periodically. As a continuous operated reactor, moving bed reactor can let both gas and solids move through the reactor, making it possible to remove the saturated adsorbents as well as deactivated catalysts. Meanwhile, fresh gas and solids can be fed into the reactor. This paper builds mathematical model of adsorptive moving bed reactor based on Claus Process. The model is simulated with Aspen Custom Modeler. Simulation results show that adsorptive moving bed reactor has good performance in Claus Process. Under the reaction conditions, the adsorption ability is limited by the temperature. Adequate increment of adsorbent volume fraction in the solids can improve the reactor’s performance.
