Abstract:

The performance of FH-98 and FH-40C catalyst developed by FRIPP in a 450 kt/a coking gasoline hydrogenation unit of PetroChina Karamay Petrochemical Co. Ltd.was compared. The results indicate that both catalysts displayed excellent activity in hydrodesulfurization (HDS) and hydrodenitrogenation (HDN). The qualities of the hydrogenated gasoline in both cases meet the feedstock requirements for reforming pre-hydrogenation unit. As FH-98 catalyst has certain cracking performance, it is easy to cause large temperature fluctuations or runaway of the bed temperature, resulting in higher operation risk. In contrast the FH-40C catalyst is found to be safer in terms of sustaining a moderate reaction temperature due to its weaker cracking capability.
