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一件设备中，以改善性能参数，例如生产率和选择性，特别是对于平衡限制反应。吸附反应器是一个很有前途的例子，多功能反应器结合了高度兼容的吸附和反应功能。吸附反应器的基本优点在于在宽温度范围内选择性吸附的应用，通过该应用，可以有意地操纵浓度和温度分布，导致反应选择性和转化率的显著提高，从而避免昂贵的尾气处理过程。本研究项目的目的是双重的：确定在颗粒水平，特别是在反应器水平的吸附反应器中的功能的集成的最佳程度，并建立一般的操作条件和操作模式下，这种最佳的集成是有利的吸附反应器的性能，以及获得一般的准则，以确定一个合适的集成度。由于吸附反应器是为环境工艺量身定制的，因此本项目将考虑两种对环境重要的反应作为测试案例：克劳斯反应，用于将从精炼粗原料中获得的硫化氢转化为硫，以及迪肯反应，用于氯化氢氧化，用于化工厂内的氯的内部循环。结构化反应器设计的新工具和新的高性能催化剂的最近可用性为吸附反应器在这两个过程中开辟了相当大的潜力。将借助系统的初步工艺设计研究和建模，辅以实验验证，开发适当改性的催化剂、吸附剂和反应器概念。
