Parallel catalytic reactors for CO/CO 2 hydrogenation, located at SINOPEC Shanghai Research Institute of Petrochemical Technology (SRIPT). Copyright: Su Liu@SRIPT Activated carbon‐supported Mo‐Co‐K sulfide catalysts, prepared by stepwise impregnation, were used in the synthesis of higher alcohols via CO 2 hydrogenation. The catalysts with Mo contents of 9∼12 wt %, a K/Mo molar ratio of 0.9, and a Co/Mo molar ratio of 0.3 showed relatively high CO 2 conversions and high selectivity to total alcohols and C 2+ alcohols. Moreover, the influence of calcination conditions on the sulfidation states and catalytic performance was studied. The surface sulfur runoff of the supported catalysts can be suppressed effectively by online calcination.
