Kinetic analysis of slurry phase Fischer-Tropsch synthesis

Fischer-Tropsch synthesis was conducted in the slurry phase using a stirred reactor and supported cobalt catalysts. Under well stirred conditions, neither the mass transfer between the gas-solid interface nor the liquid-solid interface was found to be the rate limiting step in the reaction sequence. The catalytic activity and product selectivity were markedly affected by the particle size for small pore (similar to 20 Angstrom) catalyst while those of a large pore catalyst were not affected by the particle where the partial diameter is larger than 0.1 mm. The phenomena were well simulated by theoretical calculations.
