Abstract
The present invention relates to new processes for regenerating oxidized interstitial metal hydride containing catalysts prior to the use of such catalysts in a hydroprocessing process. Interstitial metal hydride containing catalysts are easily oxidized in the environment and once oxidized, the hydroprocessing activity of the interstitial metal hydrides is most often severely diminished and this lost activity due to oxidization of the iMeH is not susceptible to recovery under hydroprocessing conditions. As a result, these catalysts in the present art require considerable special handling in inert environments all through processes from fabrication, shipping, loading, use, and maintenance of the catalyst systems to protect the activity of the interstitial metal hydride components. The present invention embodies a process regenerating oxidized interstitial metal hydride containing catalysts prior to their use in a hydroprocessing environment, thereby eliminating the requirement for maintaining the interstitial metal hydride containing catalysts in an inert environment, and allowing the handling of such catalysts in an oxidized condition prior to use.
