Qualified vendors can help you determine whether their processes are suitable for regeneration and activity recovery. They will accept confidentiality agreements to project your IP. The investigation usually starts with the HSE department checking whether the vendor can accept your catalyst on their premises. That depends on the constituents of the catalyst and any contaminants present on the spent material. If the vendor can accept your material, they will do a series of tests to develop an optimal regeneration procedure and provide samples that you may need to test before making an ultimate decision on a regeneration trial run.
