STRENGTHENED IRON CATALYST FOR SLURRY REACTORS |
摘要 |
A method of strengthening a precipitated unsupported iron catalyst by: preparing a precipitated unsupported iron catalyst containing copper and potassium; adding a solution comprising a structural promoter to the previously prepared catalyst; drying the mixture; and calcining the dried catalyst. A method for preparing an iron catalyst, the method comprising: precipitating a catalyst precursor comprising iron phases selected from hydroxides, oxides, and carbonates; adding a promoter to the catalyst precursor to yield a promoted precursor; drying the promoted precursor to yield dried catalyst; and calcining the dried catalyst, wherein the catalyst further comprises copper and potassium. A method of preparing a strengthened precipitated iron catalyst comprising: co-precipitating iron, copper, magnesium, and aluminum; washing the precipitate; alkalizing the precipitate; and drying the precipitate to yield a dried catalyst precursor. The dried catalyst precursor may be calcined and treated with a gas comprising carbon monoxide.
