Carbon supported cobalt and molybdenum catalyst and use thereof for producing lower alcohols

摘要

The present invention relates to a method for preparing a catalyst composition comprising cobalt and molybdenum on a carbon support, characterized in that the cobalt- and molybdenum-source are dissolved in an organic solvent that is miscible with water. Moreover, a carbon supported cobalt molybdenum catalyst composition obtainable by said method and a process for producing alcohols from syngas using said carbon supported cobalt molybdenum catalyst composition is provided.

主权项

1. Method for preparing a catalyst composition comprising cobalt (Co) and molybdenum (Mo) on an activated carbon support comprising the steps:
(a) dissolving a soluble cobalt-comprising compound and a soluble molybdenum-compound in one or more organic solvents that are miscible with water to form a cobalt- and molybdenum-comprising solution; (b) admixing an aqueous alkaline solution to the cobalt- and molybdenum-comprising solution in the presence of activated carbon support to precipitate an insoluble cobalt- and molybdenum-comprising compound on the activated carbon support to form a solid catalyst precursor; and (c) separating the solid catalyst precursor from the liquids, washing and drying the solid catalyst precursor and calcining the solid catalyst precursor in an inert atmosphere.
