Influence of bimodal pore size distribution of Ru/Co/ZrO2–Al2O3 during Fischer–Tropsch synthesis in fixed-bed and slurry reactor

The performance of Co/ZrO2–Al2O3 composite oxide catalyst for CH4/CO2 reforming reaction

“…It had been reported that the reducibility of catalyst depended on the nature and structure of the support [22]. In our case, for Co/Al 2 O 3 catalyst, a broad reduction peak located at 756 C was attributed to barely reducible cobalt species arising from high strength interaction of cobalt metal and alumina support [23].…”

Effects of phosphorus and saccharide on size, shape, and reducibility of Fischer–Tropsch catalysts for slurry phase and fixed-bed reactions

“…The catalysts (0.3 g) with ␣-Al 2 O 3 (1.5 g) were previously reduced in situ at 400 • C for 12 h under a flowing 5% H 2 /He reduction gas mixture at SV = 5000 mL/g cat /h. The activity tests were conducted for 120 h under the following reaction conditions: T = 220 • C, P = 2.0 MPa (gage), SV = 2000 mL/g cat /h, feed composition of H 2 /CO/CO 2 /Ar (mol%) = 57.3/28.4/9.3/5.0, where Ar was used as the internal standard for GC analysis [10,18].…”

Fischer–Tropsch synthesis over cobalt catalysts supported on nanostructured alumina with various morphologies

“…10b and d). Moreover, the presence of the stable, larger pores or bimodal pore size distribution [28,29] in Co/Al 2 O 3 -F, is likely to facilitate the diffusion of reactants and products decreasing the accumulation of high molecular weight carbon species, hence increasing the accessibility of cobalt active sites for the reaction.…”
