1/1 Summary “Methods to Controllably Produce a Hematite-containing Fischer-Tropsch Catalyst and to Produce Fischer-Tropsch Hydrocarbon Product, Product, and, Hematite-containing Fischer-Tropsch Catalyst” controllably a hematite-containing fischer-tropsch catalyst by 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; maintaining the precipitate at a retention temperature for a retention time to provide a hematite containing precipitate; and washing the hematite containing precipitate by contact with a wash solution and filtering to provide a washed hematite containing catalyst. The method may further comprise promoting the hematite-containing catalyst washed with a chemical promoter; spray drying the promoted hematite-containing catalyst; and calcining the spray dried hematite-containing catalyst to provide a calcined hematite-containing fischer-tropsch catalyst.
