| titleOfInvention | A kind of iron-based hydrogenation catalyst and preparation method thereof |
| abstract | The invention discloses an iron-based hydrogenation catalyst and a preparation method thereof. In the preparation method, the iron oxide compound is subjected to a sulfidation-oxidation reaction. During the process, the iron oxide compound and the iron-sulfur compound crystal phase undergo reconstruction and transformation, and the unit cell of the iron oxide compound also undergoes shrinkage and expansion, thereby resulting in an iron oxide that is originally structurally stable. The crystalline particles of the oxygen compound become loose and cracked, and a large amount of nano-iron compounds are produced. The nano-iron compounds have good sulfide affinity and are easily sulfided. At the same time, the surface of the nano-iron compound is covered with a non-polar elemental sulfur layer. The elemental sulfur layer can not only hinder the agglomeration and growth of the nano-iron compound particles, greatly improve its dispersibility, but also utilize the similarity between substances. Compatibility characteristics make the nano-iron compound highly dispersed in non-polar oil products, which greatly improves the catalytic hydrogenation activity of the hydrogenation catalyst. |
