Claim:
1. A method for producing a supported hematite-containing Fischer-Tropsch catalyst, the method comprising: (a) combining an iron nitrate solution with a precipitating agent solution at a precipitating temperature and over a precipitation time to form a precipitate comprising iron phases, wherein the precipitating temperature is less than or equal to 95° C.; wherein the iron nitrate, the precipitating agent solution, or both, comprise a refractory material; (b) holding the precipitate from (a) at a hold temperature of greater than or equal to 85° C. for a hold time of greater than or equal to 5 minutes to provide a hematite containing precipitate; and (c) washing the hematite containing precipitate from (b) via contact with a wash solution and filtering, to provide a washed hematite containing Fischer-Tropsch catalyst containing less than 0.3 weight percent sodium.
