Abstract

For the design of the Fischer-Tropsch catalyst, the promoter to Ru/Al2O3 catalyst was selected on the basis of the working hypothesis that fast CO bond dissociation and slow hydrogenation of surface carbon species would lead to high activity and selectivity for liquid fuel fraction. The rate constants of these surface reactions were measured by the PSRA (Pulse Surface reaction Rate Analysis) in the hydrogenation of CO on Ru/Al2O3 with several kinds of additives. Oxides of V, Nb, Mo, and W, which satisfied the working hypothesis, were selected as the promoter. The continuous flow reaction under pressure confirmed that these promoters resulted in higher activity and selectivity, indicating the effectiveness of the PSRA for the catalyst design.
