A NOVEL Cu-Fe CATALYST FOR MIXED ALCOHOLS SYNTHESIS VIA SYNGAS
1. IntroductionThe ability to develop highly active, selective, and poisoning resistant catalysts for the production of mixed alcohols is becoming increasingly important as the roles of these alcohols expand within the fuel and chemical industries. It is well known that transition metals and their oxides have been revealed significant catalytic activities. Among the transition metals and their oxides, copper, iron metals and their oxides have been exhibited as possible substitutes for precious metal catalysts on CO hydrogenation 1-3. As copper is inactive in carbide formation, it was anticipated that dilution of the iron atoms by alloying with copper atoms may be an effective procedure to suppress the formation of iron carbides and thus whisker growth. However, it has been established that the formation of (surface) iron carbides is prerequisite for iron catalysts to exhibit the desired activity in the Fischer-Tropsh reaction 4. Thus, alloying iron catalysts with inert copper may also lead to changes in the selectivity and activity.
