Summary:An influence of support morphology and Pd promoter on physicochemical properties and catalytic performance of Co/SBA-15 in Fischer–Tropsch Synthesis (FTS) was investigated. SBA-15(M) from a hydrothermal synthesis with decane addition had smaller particle size, larger pore size and shorter cavity length which enhanced the dispersion of cobalt oxides, eased diffusion of reactants and improved the FTS performance. 10Co/SBA-15(M) provided the highest and most steady conversions of CO and H2 with the highest yield of C5–C9 products. The addition of Pd enhanced the reduction of cobalt oxides but produced more methane and light paraffins. [Display omitted] •With addition of decane, SBA-15(M) had small particle and short cavity length.•Co3O4 crystallite size on SBA-15(M) was smaller than that on SBA-15.•10Co/SBA-15(M) gave the most steady, highest conversion and highest C5–C9 yield.•Pd enhanced reduction of cobalt oxides and hydrogenation but lowered chain growth.
