Abstract
The invention relates to a method for preparing low-carbon mixed alcohol catalyst from a synthesis gas and belongs to the technical field of chemicals. The method is characterized in that: a Cuo-MgO-CeO2 catalyst is prepared by using surfactant as an auxiliary material and inorganic salts of copper, magnesium and cerium as the raw materials; and C1 to C5 mixed alcohols are prepared by using the synthesis gas as a raw material gas under heating and pressurizing conditions in the presence of the Cuo-MgO-CeO2 catalyst. The Cuo-MgO-CeO2 catalyst prepared by adding the surfactant has higher activity and time space yield in the formation of the C1 to C5, than the catalyst without the surfactant, particularly the time space yield in the formation of C2 to C5 mixed alcohols is improved greatly.
