Doctoral Dissertations
Direct synthesis of dimethyl ether (DME) via CO2 hydrogenation has received great attention, owing to the global warming caused by CO2 emission and increasing energy demand worldwide. In this works, three major aspects of bifunctional catalysts development were studied: (1) investigation of the roles of interaction in the CuO-ZnO-ZrO2-Al2O3/HZSM-5 bifunctional catalysts, (2) deactivation and regeneration of CuO-ZnO-ZrO2-Al2O3 with different zeolitic catalysts for one-step CO2 hydrogenation to dimethyl ether, and (3) study on the enhancement of activity and stability of CZZA/HZSM-5 bifunctional catalysts via the introduction of …
