Industrial Adsorbents
Activated Alumina for Purification
High-performance activated alumina (γ-Al₂O₃) adsorbent and desiccant for industrial gas/liquid drying, water defluoridation, and purification. White spherical beads with high surface area (≥300 m²/g), excellent crush strength, and full thermal regenerability. Available in multiple particle sizes for compressed air dryers, water treatment, and catalyst carrier applications.
Dry adsorbent
Modified activated alumina-based adsorbent manufactured by ball-rolling process, loaded with high-content active components for simultaneous removal of H₂S and water from gas-phase and liquid-phase hydrocarbon streams. Features large pore diameter, high surface area, fast reaction kinetics, and excellent regenerability — the ideal adsorbent for impurity removal in olefin-containing feeds.
COS adsorbent
An advanced purification adsorbent catalyst based on specialty alumina with active components. Performance equivalent to imported Selexsorb COS adsorbent. Strong chemical adsorption capacity for selective removal of trace COS, CS₂, and H₂S from cracked C₂–C₄ unsaturated hydrocarbon streams. Also effectively removes CO₂, H₂O, chlorides, cyanides, and other common poisons. Operates at ambient to low temperatures for deep feedstock purification.
CD adsorbent
An advanced purification adsorbent catalyst based on specialty alumina with special modifiers. Performance equivalent to imported Selexsorb CD adsorbent. Strong chemical adsorption capacity for selective removal of trace oxygenated organic compounds (alcohols, ethers, aldehydes, ketones, peroxides) from C₂–C₄ unsaturated hydrocarbon streams in polyethylene and polypropylene units. Also effectively adsorbs water and mercaptans for deep feedstock purification. Operates at ambient to low temperatures.
Ethylene Purification Adsorbent
A CuO-ZnO adsorbent designed for the removal of CO from polymer-grade ethylene feedstock, while also removing trace amounts of O₂, H₂S, COS, AsH₃, and PH₃. Prepared by co-precipitation method with uniformly dispersed active components. Features high selectivity, high activity, excellent mechanical strength, large capacity, and easy operation. Protects polymerization catalysts from poisoning and ensures stable polyethylene production.
Propylene Purification Adsorbent
A CuO-ZnO adsorbent designed for the removal of CO from polymer-grade propylene feedstock, while also removing trace amounts of O₂, H₂S, COS, AsH₃, PH₃, and other impurities. Prepared by co-precipitation method with uniformly dispersed active components. Features high selectivity, high activity, excellent mechanical strength, large capacity, and easy operation. Protects polymerization catalysts from poisoning and ensures stable polypropylene production.
