Abstract: Through the analysis, regeneration and evaluation of the deactivated lube hydrofinishing catalyst RLF-10L of a lube hydroisomerization dewaxing unit, the primary deactivation causes were fixed, and the regeneration scheme of RLF-10L was proposed. Based on the scheme, the regeneration of RLF-10L was completed in commercial scale in SINOPEC Catalyst Company Changling Division . The analysis and evaluation results showed that the regenerated RLF-10L met the requirements of regeneration specification, and the hydrogenation activity after regeneration reached the same level of the catalyst regenerated in laboratory, indicating that the activity of the noble catalyst RLF-10L can be recovered well. This work is very important to the re-start up of the lube hydroisomerization dewaxing unit.
