Abstract

Abstract : The Co/Al2 O3 nanocatalyst prepared with tens of gram scale in a batch, showed good CO conversion (∼76%), very high CTY value (∼1.4 × 10 −4 molCO gCo −1 s −1 ) and remarkable hydrocarbon productivity (∼1.0 gHC gcat −1 h −1 ) under controlled FTS conditions. Abstract : Large-scale synthesis of cobalt nanoparticles supported on alumina (Co/Al2 O3 ), which has well dispersed metallic cobalt around 15 nm, was conducted via a simple melt infiltration process of a cobalt hydrate salt and subsequent thermal reduction. The catalytic performance of Co/Al2 O3 was studied for Fischer–Tropsch synthesis in order to optimize the liquid fuel productivity for target hydrocarbon products controlled by reaction pressures and temperatures. The catalyst showed promising CO conversions up to 76% with high hydrocarbon productivity (∼1.0 gHC gcat −1 h −1 ) and good stability.
