Effect of Cu-Fe-Co Catalyst Pretreatment in Higher Alcohol Synthesis

Abstract Higher alcohol synthesis was carried out over a CuFeCoK/SiO 2 catalyst with the focus on catalyst pretreatment methods. These methods consisted of either reduction with hydrogen, or reduction followed by low temperature carburization with CO, all at 300 °C. Furthermore, a third method was applied without any pretreatment of the catalyst. It was found that the pretreatment using both reduction and carburization gave the most active catalyst in terms of CO conversion within the temperatur
