The invention relates to a process for preparing methanol, in which a synthesis gas comprising carbon oxides and hydrogen is provided, which is passed at elevated pressure and elevated temperature through a catalyst bed of a methanol synthesis catalyst for conversion of the synthesis gas to methanol to obtain a product stream comprising crude methanol and unreacted synthesis gas. Unreacted synthesis gas is recycled to the catalyst bed inlet and combined with the synthesis gas, resulting in a mixed synthesis gas. The mixed synthesis gas at the catalyst bed inlet has a stoichiometry number SN of ≥0.80, the catalyst bed in the conversion of the mixed synthesis gas to methanol has a maximum catalyst bed temperature of ≤280° C., and the mixed synthesis gas at the catalyst bed inlet has a carbon monoxide concentration of ≤20% by volume.

The present disclosure relates to a process for converting syngas to C2+ alcohols, said process comprising the steps of providing a reactor, of providing a catalyst composition and one or more acidic materials within said reactor, of providing a feed stream comprising a mixture of H.sub.2 and CO; and of contacting said feed stream with said catalyst composition and said one or more acidic materials under reaction conditions to provide product stream. Said process is remarkable in that said catalyst composition comprises an active phase comprising CuFe deposited on a carbon-containing support, and the one or more acidic materials are one or more zeolites having a Si/Al molar ratio ranging between 2 and 200.

A catalyst including at least one group 10 metal impregnated in a mixed metal oxide is provided. The mixed metal oxide is selected from the group consisting of the oxides of In, Cu. Zn, Zr, Al, and combinations thereof. The catalyst is effective in the conversion of CO.sub.2 to value added products like methanol (CH.sub.3OH) and carbon monoxide (CO). A convenient process for preparation of the catalyst is also provided.
