Abstract

A titanium-modified γ-Al2O3 supported copper catalyst has been prepared and used for methanol synthesis by CO2 hydrogenation. The addition of Ti to the CuO/γ-Al2O3 catalyst enhances the activity in CO2 hydrogenation greatly and makes the copper in the catalyst exist in much smaller crystallites. The effect of contact time on the relative selectivity ( 6CH3OH/SCO) and selectivity of methanol was also investigated. The results indicated that methanol was formed directly from the hydrogenation of CO2.
