    • 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.
    • 本发明涉及在加氢处理方法中使用这种催化剂之前再生氧化间隙金属氢化物的催化剂的新方法。 间歇金属氢化物的催化剂在环境中容易氧化,一旦被氧化,间隙金属氢化物的加氢处理活性最多地被严重降低,并且由于iMeH的氧化而失去的活性在加氢处理条件下不易恢复。 因此,本领域的这些催化剂在惰性环境中需要相当大的特殊处理,所有这些都通过催化剂体系的制造,运输,加载,使用和维护的过程来保护间隙金属氢化物组分的活性。 本发明体现了一种在加氢处理环境中使用之前再生氧化间隙金属氢化物的催化剂的方法,从而消除了在惰性环境中维持含间隙金属氢化物的催化剂的需要,并允许在氧化条件下处理这种催化剂 使用前。
