A fundamental understanding of the precise reduction reaction pathway cobalt-based catalysts is a crucial piece knowledge in terms Fischer–Tropsch Synthesis (FTS) reaction. The use hydrogen (H2) as agent results two-stage cobalt tetraoxide (Co3O4) to oxide (CoO) and then metallic Co. objective present work apply Thermodynamic Attainable Region (TAR) catalyst using H2 so gain better insight regarding thermodynamics TAR space diagrams suggest that complete Co3O4 feasible through two pathways. Thus, observed AR temperature programmed reduction’s (TPR) first peak may be attributed direct → Co and/or an intermediate compound CoO. second result either oxides (Co3O4 or CoO Co).
