摘要: 具有3D非规则空隙结构的foam/fiber基体不仅导热性好、面体比更大,而且在消除径向扩散限制、涡流强化传质/传热、提高接触效率、几何构型灵活设计等方面显示出传统的规则2D空隙蜂窝和微通道结构难以企及的优势,但其高效催化功能化还面临挑战,近年来,相关的研究与开发日益受到重视且进展明显。本文综述了foam/fiber新型结构催化剂的"宏-微-纳"一体化"非涂层"构筑及其在涉及能源化工和环境催化等的典型强吸(放)热和/或高通量反应过程中的应用等方面的研究新进展,以期为诸如C1能源化工等众多反应过程中存在的强烈热/质传递限制等问题的解决,以及为满足环境催化和"模块"化工厂等对高通量、低压降等的特殊要求提供新的思路和技术支撑。

Abstract: The foam-/fiber-structures,with irregular 3D open network,exhibits great advantages over the traditional micro-channels/honeycombs with regular 2D voidage patterns,including free radial diffusion,vortex-driven heat/mass transfer,large area-to-volume ratio,high contacting efficiency and high flexibility in geometry design. However,highly efficient and cost-effective catalytic functionalization of such foam/fiber matrixes still remains significantly challenging. In past few years,significant efforts have been made on the nano-to macro-engineering of nanocomposites onto the foam-/fiber-structures. This review discusses the newly-developed non-dip-coating methods for the catalytic functionalization of the foam/fiber matrixes,and their applications in the strongly exo-/endo-thermic and/or high-throughput catalytic reaction processes,aiming to providing technical supports for the areas of C1 chemical,environmental catalysis and "module" chemical plants.

Key words: catalysis, reactor, heat transfer, mass transfer, structured catalyst, process intensification, foam, fiber
