Recent advances in adsorptive gas separations have focused on the development of porous materials with high operating capacity and selectivity, useful parameters that provide early guidance during the development of new materials. Although this material-focused work is necessary to advance the state of the art in adsorption science and engineering, a substantial problem remains: how to integrate these materials into a fixed bed to efficiently utilize the separation. Structured sorbent contactors can help manage kinetic and engineering factors associated with the separation, including pressure drop, sorption enthalpy effects, and external heat integration (for temperature swing adsorption, or TSA). In this review, we discuss monoliths and fiber sorbents as the two main classes of structured sorbent contactors; recent developments in their manufacture; advantages and disadvantages of each structure relative to each other and to pellet packed beds; recent developments in system modeling; and finally, critical needs in this area of research.

吸附型气体分离结构接触器的关键比较。

吸附气体分离的最新进展集中在开发具有高操作能力和选择性的多孔材料上，这些有用的参数为开发新材料提供了早期指导。尽管以材料为中心的工作对于提高吸附科学和工程技术的水平是必要的，但仍然存在一个重大问题：如何将这些材料整合到固定床中以有效利用分离。结构化吸附剂接触器可帮助管理与分离相关的动力学和工程因素，包括压降，吸附焓效应和外部热集成（用于变温吸附或TSA）。在这篇综述中，我们讨论了整料和纤维吸附剂作为结构化吸附剂接触器的两大主要类别。其制造的最新发展；每种结构相对于彼此和粒料填充床的优缺点；系统建模的最新发展；最后，该研究领域的关键需求。
