Abstract:

The hydrotreating catalyst used in lubricating oil production under high pressure was regenerated for its lower activity. The activity of the regenerated catalyst is found lower than that of the fresh one. The medium-pressure hydrotreating and hydrodeacidification performance of the regenerated catalyst were evaluated in the laboratory. The results show that the regenerated catalyst can achieve the product specifications of medium-pressure hydrotreating and hydrodeacidification processes. This recycling program improves the utilization of the regenerated catalyst and makes a better benefit for the refinery.

Key words: lube base oil, high-pressure hydrotreating, catalyst, regeneration, hydrodesulfurization
