Arsine is known as one of the most poisons to downstream catalyst in hydrocarbon processing, which is present in ppb level in propylene stream can poisons the downstream precious metal catalyst in polypropylene production. Also Natural gas frequently contains arsine and other arsenic compounds that some of the type are not effectively removed with a traditional adsorbent.
Chempack offers serial arsine guard catalyst to meet the update requirements. The choice of the specific catalyst portfolio depends on the feed stream characteristics, type of impurity to be removed, and the process conditions such as the pressure, temperature etc. Arsine can be removed at ppb levels by using our Arsine Removal Catalyst.
