项目摘要

In multifunctional reactors, chemical reactions and unit operations are integrated into a single piece of piece of equipment, in order to improve performance parameters, such as productivity and selectivity, particularly for equilibrium-limited reactions. Adsorptive reactors represent a promising example of multifunctional reactors incorporating the highly compatible adsorptive and reactive functionalities. The fundamental advantage of adsorptive reactors lies in the application of selective adsorption over a wide temperature range, by which concentration and temperature profiles can be deliberately manipulated leading to considerable enhancement of reaction selectivity and conversion and thus avoiding expensive tail-gas treatment processes. The objective of this research project is twofold: to determine the optimal degree of integration of functionalities in adsorptive reactors at the pellet level and especially at the reactor level and to establish general criteria for the operating conditions and operating modes under which this optimal integration is favorable for adsorptive reactor performance as well as to derive general guidelines for determining a suitable degree of integration. As adsorptive reactors are tailor-made for environmental processes, two environmentally important reactions will be considered as test cases in this project: the Claus reaction for converting the hydrogen sulfide obtained from refining crude raw materials to sulfur and the Deacon reaction for hydrogen chloride oxidation used for the internal recycling of chlorine within chemical plants. The recent availability of novel tools for structured reactor design and of new high performance catalysts has opened up considerable potential for adsorptive reactors in these two processes. Appropriately modified catalysts, adsorbents and reactor concepts will be developed with the help of systematic preliminary process design studies and modelling complemented by experimental validation.

在多功能反应器中，化学反应和单元操作被集成到单个设备中，以提高性能参数，例如生产率和选择性，特别是对于平衡限制反应。吸附反应器代表了多功能反应器的一个有前途的例子，它结合了高度兼容的吸附和反应功能。吸附反应器的根本优势在于在较宽的温度范围内应用选择性吸附，可以有意地控制浓度和温度分布，从而显着提高反应选择性和转化率，从而避免昂贵的尾气处理过程。该研究项目的目标是双重的：确定吸附反应器在颗粒水平，特别是在反应器水平的功能集成的最佳程度，并建立操作条件和操作模式的一般标准，在该标准下，这种最佳集成有利于吸附反应器的性能，并得出确定合适集成程度的一般准则。由于吸附反应器是为环境过程量身定制的，因此该项目将考虑两个对环境重要的反应作为测试案例：将精炼粗原料中获得的硫化氢转化为硫的克劳斯反应和用于化工厂内氯气内部循环的氯化氢氧化的迪肯反应。最近出现的用于结构化反应器设计的新颖工具和新型高性能催化剂为吸附反应器在这两个过程中开辟了巨大的潜力。借助系统的初步工艺设计研究和建模并辅以实验验证，将开发适当改进的催化剂、吸附剂和反应器概念。
