采用新结构的催化/吸附填料来发展反应过程强化技术是当前寻求节能减排、环境友好和安全生产的重要途径之一.新型微纤结构填料可将大空隙率、小尺度(颗粒)、多孔结构、大比表面积、良好导热性和渗透性以及独特的形状因子等有利于改善反应/吸附床层传质/传热和几何构型灵活设计的诸多要素一体化.综述了微纤结构填料在能源催化、选择氧化、空气过滤和电化学储能材料制备等方面的研究进展,并对微纤结构填料的发展方向和应用前景进行了展望.
Process intensification draws a lot of attention because it is working towards energy savings,waste emission reduction,time reduction,and safety improvement.Novel microfibrous structured packings provide a unique combination of large void volume,entirely open structure,large surface-to-volume ratio,high permeability,high heat/mass transfer,and unique form factors,which are central to the notion of increasing the steady-state volumetric reaction rate.The latest progress in the use of microfibrous structured packings in H2 fuel generation and cleanup,air filtration,selective oxidation,electrochemical energy storage,and F-T synthesis has been reviewed.The prospects for the microfibrous structured packings towards process intensification were also presented.
