摘要 |
A pelleted iron oxide catalyst precursor wherein the iron oxide has an O/Fe atomic ratio in the range 1.2 to 1.4, a high surface area and a density of at least 2.6 g.cm-3. The precursor may be made by de-oxidizing, by heating in the presence of a steam/hydrogen mixture, an iron oxide composition made by precipitation and calcination, followed by pelleting after-de-oxidation. |
