High Temperature Water Permeable Membrane Reactors for CO2 Utilization

• Membrane for water/gases separation under high temperature and pressure is reviewed. Water permeable membrane reactors applied in various CO 2 hydrogenations The mechanism of harsh conditions discussed. Key requirements zeolite membranes applying hydrogenation Converting to valuable chemicals via catalytic presents a promising way utilization. However, many types are generally conducted (T?200 °C P?20 bar), yet these reactions limited by thermodynamic equilibrium. common by-product reactions. By employing water reactor simultaneously remove from the reaction, not only favors higher conversion overcoming limitation equilibrium, but also protects catalyst deactivation caused water. development suitable this application has received huge attention worldwide. gases (H , CO) major challenge developing good performance membrane. Herein, review contains separating membranes, their applications reaction discussed detail. Furthermore, challenges prospects type provided future development.
