摘要：
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 PH2O/PH2 ratio and the PH2O/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 PH2O/PH2 and PH2O/Z ratios substantially equal to or lower than 0.8.
