Spent catalyst re-use

Spent catalyst re-use

At the end of the catalyst cycle, the spent catalyst needs to be unloaded for reuse, or elimination. It is important to prepare the shutdown carefully to ensure that the spent catalyst is conditioned optimally for further processing. After the shutdown, specialised catalyst-handling companies will unload the reactor. It is important to keep track of the location inside the reactor where the catalyst originated. It is a best practice to number the drums per reactor bed and identify the catalyst types, drum number and reactor and bed IDs on a clear label. This will help with cost-effective analysis of the spent catalyst and in distinguishing between a good-quality catalyst for reuse and a contaminated catalyst for elimination.

Catalyst Intelligence can advise on unloading strategy, packaging and labelling of the spent catalyst, plus analysis of the spent catalyst and laboratory analysis and regeneration to determine suitability of the material for reuse. After regeneration and/or rejuvenation, the catalyst destined for reuse should be sampled and analysed to determine whether the service provider has met the guarantees.
