1. comprise the activation method of the iron-based fischer-tropsch catalyst of the iron being in positive oxidation state, the method is passed through at least 245 DEG C and lower than at the temperature of 280 DEG C, higher than 0.5MPa and under the reducing gas pressure being not more than 2.2MPa, and at the GHSV being fed to the total gas in reactor under at least 6000ml (N)/g catalyst/h, make described ferrum-based catalyst in the reactor and be selected from CO and H 2/ CO mol ratio is the H of 100:

  • 1 to 1;

    100 2contact with the reducing gas of the combination of CO, thus reduce the iron being in positive oxidation state in described catalyst.
