Claim Text:
1. A method for preparing synthetic liquid hydrocarbons by catalytic conversion of a syngas according to the Fischer-Tropsch synthesis in a multilayer fixed bed of granulated catalysts comprising: passing a reaction mixture sequentially through at least four layers of said fixed bed, wherein: a first layer in the direction of passing the reaction mixture comprises a cobalt Fischer-Tropsch synthesis catalyst that comprises skeleton cobalt and that catalyzes Fischer-Tropsch synthesis at an Anderson-Schulz-Flory factor of 0.67 to 0.96, wherein the first layer has thermal conductivity of not less than 4 W/m/K, a second layer in the direction of passing the reaction mixture comprises a cobalt Fischer-Tropsch synthesis catalyst that catalyzes Fischer-Tropsch synthesis at an Anderson-Schulz-Flory factor of 0.82 to 0.96, a third layer in the direction of passing the reaction mixture comprises not less than 30% of H-form zeolite, and a lowermost layer comprises a cobalt Fischer-Tropsch synthesis catalyst that catalyzes Fischer-Tropsch synthesis at an Anderson-Schulz-Flory factor of 0.82 to 0.96.
