Process for maintaining the stability of performances of a catalyst for Fischer-Tropsch reaction, performed in a slurry bubble column reactor under a triphase system, which comprises gradually increasing the PH20/PH2 ratio and the PH20/Z ratio, during the start-up phase, with Z = P0 (T/T1)4 e-(K2/(t K3)) from 0.4 to 0.8, for a period of time not shorter than 100-150 hrs and not longer than 200-300 hours and, at the end of the start-up phase, maintaining the PH20/PH2 and PH20/Z ratios substantially equal to or lower than 0.8.
