Poison control

Poison control Inorganic contaminants of refinery feedstocks are often poisons for hydroprocessing catalysts. The source of these contaminants is often the crude itself, with different contaminants associated with various crude sources. Some contaminants are introduced during normal refining processes or from upset conditions.

Control of poisons is accomplished by using catalysts with high capacity to adsorb contaminants at the top of the catalyst bed. These sacrificial catalyst layers protect downstream catalysts from the poisoning effects, allowing them to retain their high activity for a longer time and increase cycle length. Catalysts have been developed which work particularly well to adsorb specific contaminants.
