The catalyst is an improved high-efficiency purification adsorption catalyst. It uses special alumina as a carrier and adds a special modifier. It can be used at normal and low temperatures, and its performance is equivalent to that of imported selexsorb CD adsorbent. Due to the strong chemical adsorption on the surface of the adsorbent, it can crack polyethylene and polypropylene devices to crack C2-C4 hydrocarbons and multi-unsaturated monomer raw materials, and trace oxygen-containing organic compounds (alcohols, ethers, Aldehydes, carboxyl compounds, ketones, peroxy compounds) are directly and selectively removed by adsorption. At the same time, it also has a good adsorption effect on the water and mercaptans in the raw materials, which meets the requirements of deep purification of the raw materials.
