IRON-BASED FISCHER-TROPSCH CATALYST AND METHOD FOR MAKING THE SAME

摘要

An iron-based Fischer-Tropsch catalyst comprises Fe, Mn, K and Cu, with an Fe/Mn molar ratio less than 7:3, Cu loading approximately 0.5wt%, and K loading about equal to or less than 1 wt%. An iron-based Fischer-Tropsch catalyst comprises Fe, Mn, K and Cu, with an Fe/Mn molar ratio in a range of about 5:5 to about 6:4, K loading in a range of about 0.4wt% to about 2.2 wt%, and Cu loading about 0.5wt%. The catalysts shows significantly higher CO conversion and significantly lower selectivity for CO2 in a Fischer-Tropsch process compared with conventional catalysts.
