PROMOTED, ATTRITION RESISTANT, SILICA SUPPORTED PRECIPITATED IRON CATALYST |
摘要 |
A catalyst support solution for improving the attrition resistance of a Fischer-Tropsch catalyst, the solution comprising: crystalline silica and at least one chemical promoter selected from alkali metal bases, wherein the support solution has a pH of greater than or equal to about 7. A structurally promoted catalyst comprising: crystalline silica; at least one basic chemical promoter; and iron; wherein the catalyst comprises SiO2:Fe in a ratio of from about 2:100 to about 24:100. A method of producing a structurally promoted precipitated iron catalyst, the method comprising: forming the structural support solution described above; stirring the support solution for a time to dissolve the silica in the solution; adding the support solution to a precipitated iron catalyst slurry to form an attrition resistant catalyst slurry; and drying the attrition resistant catalyst slurry to yield the structurally promoted precipitated iron catalyst. |
