The conversion of syngas to mixed higher alcohols has attracted much attention in the field of energy and chemical engineering during the past decades. High performance catalysts and efficient separation process are key technologies for industrial large-scale application. This paper summarizes the latest research progress of process and catalyst for higher alcohols synthesis,in which catalytic systems including modified methanol catalysts,modified Fischer-Tropsch catalysts, MoS2-based catalysts and other catalysts are well reviewed. A promising route to improve catalytic performance in mixed higher alcohols synthesis is proposed by controlling the structure and composition of catalyst precisely,so as to increase stability and selectivities. The trend of conversion of syngas to mixed higher alcohols directly is also suggested by coupling of multi-reactions and processes.
