The catalyst is improved efficient purification absorptive catalyst, it can be used at normal and low temperature with special modifier added and special aluminium oxide as carrier, and its performance is equal to the imported selexsorb CD absorbent. Because the adsorbent surface has very strong chemical adsorption effect, it can directly and selectively absorb and remove trace amount of oxygen-containing organic compounds (alcohol, ether, aldehyde, carboxyl compound, ketone, peroxide) in cracking C₂-C₄ hydrocarbon multiple unsaturated monomer raw material and co-monomer material of polyethylene and polypropylene devices, and it also has good adsorption effect on water and mercaptans in raw materials to reach the deep purification requirement for raw materials.

Industrial application
Because the product is characterized by low operating temperature, simple operation, obvious purification effect and energy saving and consumption reduction, it brings large economic benefit to users. It successfully replaces the imported selexsorb CD to realize localization in Baling Petrochemical Corp, Dushanzi Ethylene Plant, Shenhua Baotou Coal Chemical Company and other enterprises, so it has extremely wide application prospect.
