摘要： 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 H2 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.

摘要： The invention relates to a process for methanol synthesis comprising the steps of providing a syngas feed stream comprising hydrogen and carbon oxides selected from carbon dioxide or a mixture of carbon dioxide and carbon monoxide, wherein carbon dioxide represents from 1 to 50 mol % of the total molar content of the feed stream, carbon monoxide is contained from 0 to 85 mol % of the total molar content, and H2 is comprised from 5 to 95 mol % of the total molar content of the feed stream, and a catalyst comprising indium oxide (In2O3) on a support wherein the support comprises zirconium dioxide or is zirconium dioxide; putting in contact said stream with said supported catalyst at a reaction temperature of at least 373 K (99.85° C.) and under a pressure ranging of at least 1 MPa; and recovering the methanol effluents. The invention also relates to a supported indium oxide catalyst.
