CATALYST FOR FISCHER-TROPSCH SYNTHESIS AND ITS PREPARATION METHOD

摘要

In a method of making an iron-based catalyst for Fischer-Tropsch Synthesis with elements Fe, Mn, K, and Cu, a Fe, Mn nitrates solution is mixed with an ammonium glycolate or ammonium citrate solution to obtain a slurry material. The slurry material is processed to obtain a dry material, which is then impregnated with K and Cu to obtain a material containing Fe, Mn, K and Cu, which is further processed to obtain an iron based catalyst. The catalyst prepared by the method when applied in Fischer-Tropsch-Synthesis reactions can help achieve a high CO conversion and low CO2 selectivity for the reactions.
