CATnapTM catalyst passivation process - an alternative to inert entry

Cat Tech is pleased to present the CATnap® Catalyst Passivation Process - an exclusive, patented technique for unloading catalysts from petroleum processing units. CATnap technology passivates pyrophoric or self-heating catalysts by the application of a proprietary CATnap catalyst coating chemical. The catalysts’ surfaces (and equipment surfaces are coated with an organic film which retards oxygen penetration and reaction.

The passivated catalyst can be unloaded under air, thus eliminating many of the hazards and expenses related to inert entry.
