Abstract: The present subject matter relates generally to methods and an apparatus for catalyst sampling for measuring and testing. More specifically, the present subject matter relates to methods for sampling a catalyst where solid material samplers are used in between reactors or regeneration zones to gain knowledge of the state of the catalyst at different points in the hydrocarbon conversion process.
