ABSTRACT:
Catalysts comprising iron carbide on a surface modified titania support wherein said support comprises a surface modifying oxide of tantalum, niobium, vanadium and mixtures thereof supported on said titania wherein at least a portion of said surface modifying oxide is in a non-crystalline form. These catalysts are useful for Fischer-Tropsch hydrocarbon synthesis reactions. Preferably, at least about 25 wt. % of said surface modifying oxide will be in a non-crystalline form.
