  • To support the design of commercial scale reactor and process optimization for Fischer-Tropsch synthesis (FTs),a lumped mechanism kinetic model of CO conversion was established over the commercial iron-based catalyst CNFT-1 (Fe-Cu-K-B-Si,bulk density:0. 8 g / cm3 ). Firstly,the LHHW kinetics model of CO conversion was de- rived based on the classical and widely accepted carbide mechanism and the assumption of methylene formation reac- tion as rate determining step. 30 sets of kinetic data were obtained from a 1L continuously stirred tank reactor (CSTR,H / D ratio was 2. 5) experiments,which were conducted under the conditions of eliminating diffusion effect related to intra-particle and external,i. e. agitation speed > 400 r / min,GHSV >7 000 mL / ( g·h) and catalyst particle size
