Project ID: FY19-3
To develop a catalytic membrane reactor (with high selectivity and flux) to remove by- product (H2O) and concentrate methanol yield; to overcome the thermodynamic equilibrium limitation.
A major challenge of converting CO2 to methanol through hydrogenation is the thermodynamic equilibrium limitation of the methanol yield. In this project, we aim to couple the CO2 hydrogenation reaction with continuous pervaporative separation of water with our highly selective zeolite hollow fiber membranes. The pore size, conditions of coating and other parameters will be optimized to increase the selectivity and permeation flux. The interaction and compatibility between catalysts and zeolite membranes will also be investigated under various gas atmospheres at high temperature of 200~300˚C.
