The PK-3SHN catalyst is designed to purify carbon dioxide from combustible impurities (CH4, H2). APN-Sh and APN catalysts are designed to purify gases (argon, nitrogen) from oxygen. They are metallic palladium deposited on the surface of active aluminum oxide with a highly developed surface. PC-3SH and APN-Sh catalysts are available in the form of spherical granules. APN is available in the form of cylindrical granules.
