More Information
Summary:The invention relates to a precipitated ferrum-cobalt catalyst for Fischer-Tropsch synthesis, a preparation method and application thereof. The catalyst comprises an iron element (Fe) used as a main catalyst (100g is used as a benchmark); the catalyst also comprises a cocatalyst, wherein the cocatalyst comprises the following components: 2 to 50g/100g of Fe in cobalt element, 1 to 10g/100g of Fe in potassium element and 5 to 100g/100g of Fe in substance containing silicon and oxygen by weight of silicon dioxide. Compared with the prior art, the precipitated ferrum-cobalt catalyst has the advantages of higher gas percent conversion, higher productive rate of products and higher catalyst stability.
