Conversion of syngas to mixed alcohols over K-Mo-S/activated carbon.

Abstract

The present work reported the catalysts were prepared from activated carbon impregnated with K₂CO₃ and MoO_x and investigated for the synthesis of mixed alcohols from syngas. Two catalyst samples have different MoOx loadings of 15 - 30 wt%. The solids were characterized by XRD, SEM, H₂-TPR and BET techniques. An increased Mo loading results in a decreased surface area of the solid. After sulfidation with H₂S/H₂, the catalysts are tested for the synthesis of alcohols from syngas and show a high CO conversion at values of 10-23%. The predominant product is ethanol with the selectivity of 25-45% at typical reaction conditions.
