FIELD: chemistry.SUBSTANCE: claimed invention relates to Fe-based catalyst for Fischer-Tropsch synthesis, method of its manufacturing and application. Described is Fe-based catalyst for Fischer-Tropsch synthesis, which contains Fe as main component, with catalyst also containing: oxide(s) of Cu and/or Ag metal as reduction activator; at least, one oxide of metal M from IA group as electronic activator, with metal M from IA group being selected from Li, Na, K or Rb; at least, one noble metal M' of group VIII as hydrogenation activator, with noble metal M' of group VIII being selected from Ru, Rh, Pd or Pt; and SiOas structure activator; and main component Fe is represented in form of its complete oxide, with Fe content in final catalyst constituting 30% wt - 70% wt. Described is method of manufacturing, consisting of the following stages: preparation of Fe salt solution; fast co-precipitation with alkaline compound, then, washing and repulpation; addition of group IB metal salt solution as reduction activator, group IA metal salt solution and silica sol, or addition of IB group metal salt solution as reduction activator and group IA metal silicate; after that, dehydration by drying via dispersion, impregnation in solution of salt of group VIII noble metal, drying and burning to obtain catalyst. Described is method of obtaining hydrocarbons by low-temperature Fischer-Tropsch synthesis with application of described above catalyst.EFFECT: high output of heavy hydrocarbons, low methane selectivity and decrease in olefins selectivity.16 cl, 1 tbl, 6 ex |
