Abstract

The combination of Cu-based catalysts and acidic zeolites were evaluated for dimethyl ether (DME) synthesis from a mixture of CO₂-H₂. The physical mixture of Cu/amorphous ZrO₂ catalyst and protonated FER-type zeolites yielded a higher selectivity of DME compared to a Cu/ZnO/Al₂O₃ catalyst and FER-type zeolite at 1 MPa. Cu/amorphous ZrO₂ demonstrated relatively low activity in terms of undesirable CO formation. The combination of FER-type zeolite and Cu/amorphous ZrO₂ catalyst showed good activity for methanol dehydration, resulting in the high production of DME. DME selectivity over the combination of Cu/amorphous ZrO₂ and FER-type zeolite reached nearly 40%.
