In addition to aromatics, there are also olefins, dienes and sulfur in cracking C9. In order to make better use of C9, desulfurization and dealkylation are needed. Our company has developed C9 hydrogenation technology for a long time. After hydrogenation, the product color is colorless and has good stability. It can produce high octane gasoline blending components, solvent oil or extracted aromatics. The picture shows the C9 hydrogenation unit of Danyang Liandong Chemical Co., Ltd.
