Highly active and stable catalytic performance on phosphorous-promoted Ru/Co/Zr/SiO2 Fischer–Tropsch catalyst

A novel doubly promoted Ru/Co/ZrP/SiO2 catalyst with zirconium–phosphorous species (ZrP) reveals high activity and stability on Fischer–Tropsch synthesis (FTS). The surface modification of SiO2 with ZrP species containing appropriate amount of phosphorous component, has an effect on the suppression of cobalt particle aggregation during FTS reaction. The spatial confinement of cobalt particles in ZrP matrix could be significantly enhanced when P/(Zr + P) molar ratio is around 0.13 (CoZrP(0.5)).
