Production of Higher Alcohols from Synthesis Gas over Coprecipitated Nickel Catalysts

Abstract

Coprecipitated Ni–TiO2 and Ni–MnO catalysts efficiently produced higher alcohols such as ethanol, propanol and butanol from synthesis gas. These catalysts showed lower activities for ethane hydrogenolysis but much higher activities for ethylene hydroformylation than conventional supported nickel catalysts.

Catalytic Conversion of Syngas into Higher Alcohols over Carbide Catalysts

“…Cu addition to Mo 2 C was also observed to lower the hydrocarbon selectivity in CO 2 hydrogenation . The use of manganese as a support or promoter has been reported to benefit the alcohol synthesis over a wide variety of catalytic systems. − Promotion by rhenium has been reported to benefit the ethanol selectivity in CO hydrogenation over Co-based catalysts. , Promotion by La and V has been reported to boost the ethanol selectivity of rhodium . Table summarizes the activities and selectivities of various multiply promoted carbide catalysts, while Figure illustrates the space time yields of various product classes for the promoted Mo 2 C catalysts.…”

“…Nevertheless, these nickel systems are often SiO2-supported [2] or coprecipitated (Ni-TiO2, Ni-MnO) [3].…”
