摘要
结构化催化剂与反应器(SCR)是当前催化与化工交叉领域的研究热点和国际前沿。提出了金属Foam/Fiber基体"非涂层"原位催化功能化的"宏-微-纳"全链条Top-Down逆向设计策略,原创性地构建了湿式化学刻蚀、原电池反应置换活化、分子筛原位生长、偶联剂辅助自组装等的结构催化剂制备新方法和新技术,突破了"涂层技术"通适性差的局限性,将结构催化剂从规则2D空隙蜂窝和微通道结构拓展到了非规则3D空隙金属Foam/Fiber等结构,为强化热-质传递和高通量、低压降操作提供了新技术途径,在合成天然气(SNG)、CH4/VOCs催化燃烧、DMO加氢、MTP等能源与环境催化过程的应用中得到有力验证。
Development and use of the structured catalysts and reactors(SCRs) is a promising strategy to overcome the major drawbacks encountered in the traditional packed-bed reactor due to improved hydrodynamics in the combination with enhanced heat/mass transfer,thus being a hot topic in the heterogeneous catalysis.Recently,one-step and efficient non-dip-coating "Top-Down" SCRs design has been successfully demonstrated for a synergistic coupling of the improved hydrodynamics and enhanced heat/mass transfer in the packed-bed reactor(Top) with the catalytic reaction on catalyst surface(Down),using 3D metallic foam/fiber substrates rather than 2D microchannel-structured honeycombs.Here,the latest progress in Foam-/Fiber-based SCRs development,according to the Top-Down design principle,to be used in strongly exo-/endo-thermic and/or high throughput reaction processes such as SNG,CH_4/VOCs combustion and DMO hydrogenation,has been summarized.
