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.

摘要: A method of producing an iron catalyst for catalyzing the hydrogenation of carbon monoxide is disclosed. The method comprises using a reduced amount of acid for iron dissolution compared to certain previous methods. The resulting acidic iron mixture is heated without boiling to obtain a nitrate solution having a Fe2+:Fe3+ ratio in the range of about 0.01%:99.99% to about 100%:0% (wt:wt). Iron phases are precipitated at a lower temperature compared to certain previous methods. The recovered catalyst precursor is dried and sized to form particles having a size distribution between 10 microns and 100 microns. In embodiments, the Fe2+:Fe3+ ratio in the nitric acid solution may be in the range of from about 3%:97% to about 30%:70% (wt:wt) and the calcined catalyst may comprise a maghemite:hematite ratio of about 1%:99% to about 70%:30%.
