吸附反应器作为一种提高多相催化气相反应选择性和转化率的混合过程，其概念引起了人们的广泛关注。催化剂和吸附剂颗粒在反应器内的不均匀分布可提高吸附反应器的性能，本文提供了确定适当分布的一般准则。以克劳斯过程及其参数变量为测试用例，进行了仿真和优化研究。研究表明，催化剂和吸附剂的不均匀分布有利于提高吸附反应器的性能。它还表明，对于最佳吸附反应器性能来说，非均匀分布并不总是必需的，在某些条件下，简单的均匀分布就足够了。
The concept of adsorptive reactors has attracted considerable attention as a hybrid process to enhance reaction selectivity and conversion for heterogeneously catalyzed gas-phase reactions. The performance of adsorptive reactors may be enhanced by the nonuniform distribution of catalyst and adsorbent particles within the reactor and general guidelines for determining a suitable distribution are provided in this article. Simulation and optimization studies have been carried out using Claus process and its parametric variants as test cases. The study indicates the conditions under which a nonuniform distribution of catalyst and adsorbent is favorable for adsorptive reactor performance. It also shows that a nonuniform distribution is not always essential for the optimal adsorptive reactor performance and that under certain conditions a simple homogeneous distribution may well suffice.
