The regenerated catalyst may also imdergo rejuvenation, a wet process in which the active metals are chemically re-dispersed. A combination of regeneration and rejuvenation can restore a catalyst to more than 95% of its original activity. 

Inevitably, some particles break apart during the unloading, transportation, regeneration, and rejuvenation of spent catalysts. If part of the catalyst is
