This invention improves prior methods of making cobalt-molybdenum-sulfide catalysts for alcohol production from syngas. In one aspect, improved methods are provided for making preferred cobalt-molybdenum-sulfide compositions. In another aspect, processes utilizing these catalysts for producing at least one C1-C4 alcohol, such as ethanol, from syngas are described.

The invention herein provides methods of activating a catalyst composition. These methods include annealing a catalyst with an inert gas, under effective conditions, and then contacting the annealed catalyst with syngas to produce an activated catalyst. These steps can also be reversed. The activated catalysts can be employed to convert syngas into products, such as alcohols, with improved selectivities and yields.

This invention provides a method for producing ethanol and 2-propanol from syngas, the method comprising: (a) converting syngas into methanol using a methanol-synthesis catalyst; (b) converting methanol into ethylene and propylene using a methanol-to-olefins catalyst; and (c) hydrating ethylene into ethanol and propylene into 2-propanol. As taught herein, the combined yield of the ethanol and the 2-propanol from biomass can be at least 100 gallons per dry ton biomass. In certain embodiments, the yield of ethanol is at least 100 gallons per dry ton biomass. In some embodiments, the yield of 2-propanol is at least 50 gallons per dry ton biomass.
