Abstract:
1. A structurally promoted, precipitated, Fischer-Tropsch catalyst that exhibits an RCAI-10 in the range of from about 0 to about 2.8, produced by a method comprising: preparing a nitrate solution, wherein preparing comprises forming at least one metal slurry and combining the at least one metal slurry with a nitric acid solution; combining the nitrate solution with a basic solution to form a precipitate; structurally promoting the precipitate with at least one source of silicon to form a promoted mixture, wherein promoting comprises combining the precipitate with (a) silicic acid and one or more component selected from the group consisting of non-crystalline silicas, crystalline silicas, and sources of kaolin or (b) at least one component selected from the group consisting of non-crystalline silicas and sources of kaolin, in the absence of silicic acid; and spray drying the promoted mixture to produce a spray-dried catalyst having a particle size.
