A method of activating an iron Fischer-Tropsch catalyst by introducing an inert gas into a reactor comprising a slurry of the catalyst at a first temperature, increasing the reactor temperature from the first temperature to a second temperature at a first ramp rate, wherein the second temperature is in the range of from about 150 DEG C to 250 DEG C, introducing synthesis gas having a ratio of H2:CO to the reactor at a space velocity, and increasing the reactor temperature from the second temperature to a third temperature at a second ramp rate, wherein the third temperature is in the range of from about 270 DEG C to 300 DEG C. The iron Fischer-Tropsch catalyst may be a precipitated unsupported iron catalyst, production of which is also provided. |
