文摘

The concept of adsorptive reactors has attracted considerable attention as a hybrid process to enhance reactionselectivity and conversion for heterogeneously catalyzed gas-phase reactions. The performance of adsorptivereactors may be enhanced by the nonuniform distribution of catalyst and adsorbent particles within the reactorand general guidelines for determining a suitable distribution are provided in this article. Simulation andoptimization studies have been carried out using Claus process and its parametric variants as test cases. Thestudy indicates the conditions under which a nonuniform distribution of catalyst and adsorbent is favorablefor adsorptive reactor performance. It also shows that a nonuniform distribution is not always essential forthe optimal adsorptive reactor performance and that under certain conditions a simple homogeneous distributionmay well suffice.
