Abstract. The influence of cobalt particle size in the range 3 to 18 nm on the Fischer–Tropsch synthesis intrinsic activity and product distribution was investigated over 26 alumina (γ -Al2O3 and α-Al2O3) supported catalysts. A volcano-like curve was obtained for the γ -Al2O3 based catalysts when the C5+ selectivity was plotted as a function of the particle size. The maximum selectivit…
Abstract. Co, Mo, NiMo and CoMo catalysts supported on alumina, fishbone and platelet carbon nanofibers (CNFs) have been prepared. The dispersion of the oxide phases was qualitatively studied and compared using Xray diffraction (XRD) and transmission electron microscopy (TEM). The reducibility of the catalysts was studied by temperature programmed reduction (TPR). Hydrodesulfurization (HDS)…
