Description

Technical field:

[0001] The invention relates to an iron / manganese catalyst and a preparation method thereof, in particular to an iron / manganese catalyst for Fischer-Tropsch synthesis and a preparation method thereof. Background technique:

[0002] Iron-based catalysts are the most commonly used type of Fischer-Tropsch synthesis catalysts. Because of their high water-gas shift activity, they are especially suitable for Fischer-Tropsch synthesis reactions using coal-based synthesis gas with low hydrogen-to-carbon ratios as raw materials. At present, the Sasol company in South Africa, which has successfully realized the large-scale industrial operation of Fischer-Tropsch synthesis, uses an iron-based catalyst (M.E.Dry et al, Catalysis Today, 1990, 6(3)183-206).
