摘要：
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 H-2 with the highest yield of C-5-C-9 products. The addition of Pd enhanced the reduction of cobalt oxides but produced more methane and light paraffins. (C) 2014 Elsevier B.V. All rights reserved.
