RAs998 arsenic removal agent
■Product features and application rangeRAs998 arsenic removal agent is a copper-based arsenic removal agent. It is mainly used for arsenic removal of propylene, ethylene and other raw materials. It has the characteristics of good arsenic removal, large arsenic removal capacity and convenient use. The comprehensive performance has reached the level of imported catalyst. Arsenic removal principle of RAs998 arsenic removal agent: Arsine (AsH3) in liquid propylene reacts with copper oxide to form arsenic arsenide, elemental arsenic, and part of new copper and arsenic alloy is formed, and AsH3 is removed from the raw material to protect The purpose of the polymerization catalyst.3CuO+2AsH3 → Cu3As+As+3H2O3CuO+2AsH3 → 3Cu+2As+3H2O
