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. Fischer–Tropsch synthesis (FTS) at 20 bar and 483 K, with H2-poor syngas (H2/CO ratio = 1.0) in order to simulate gasified biomass, was performed over Al2O3-supported catalysts with various ratios of Fe:Co (12 wt% bimetal) prepared by co-impregnation. Co was found to be incorporated into the Fe2O3 phase after calcination, at least for the iron-rich samples, while no evidence of …
