The PROBACAT® sampling method enables catalyst sampling without reactor unloading requirement.

It collects catalyst samples from a fixed bed reactor in a vertical (15 meters) or oblique (4 meters) plane.


The main advantage of this sampling method is the possibility to determine the quality of the catalyst at a localized point of the reactor. This can be useful to determinate :
Poisoning / contamination profile (metallic content).
Unloading / screening strategy.
Catalyst regeneration identification.
Evaluation of the homogeneity of feed distribution, by taking samples over the cross-section of the catalyst bed.
