Catalytic membrane reactors for carbon peaking and carbon neutrality

Catalytic membrane reactors have the advantages of allowing the selective removal of products, avoiding the separation procedure of powder catalysts from the reaction mixture, intensifying the diffusion of reactants in the catalytic region, and integrating different reactions in one unit. Catalytic membrane reactors have been widely applied in the fields related to carbon peaking and carbon neutrality, including the capture and utilization of carbon dioxide, hydrogen production, and hydrogenation reaction. This review summarizes the design and fabrication of catalytic membrane reactors, with the focus on the capture and efficient utilization of carbon dioxide, hydrogen production and efficient liquid-phase hydrogenation. The design of membrane materials, catalyst materials and catalytic membranes, and the operation of catalytic membrane reactors are discussed respectively. Finally, the perspectives and future challenges of catalytic membrane reactors for carbon peaking and carbon neutrality are forecasted.
