  • CATALYST FOR LOW TEMPERATURE SLURRY BED FISCHER-TROPSCH SYNTHESIS
    Publication number: 20170209852
    Abstract: A method for controllably producing 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; holding the precipitate from at a hold temperature for a hold time to provide a hematite containing precipitate; and washing the hematite containing precipitate via contact with a wash solution and filtering, to provide a washed hematite containing catalyst. The method may further comprise promoting the washed hematite containing catalyst 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.
    Type: Application
