The catalyst is a high-efficiency purification catalyst prepared by co-precipitation method with active copper, zinc and other components, and can be used to remove petroleum gas and trace carbon monoxide in inert gas. It can also be used to remove trace CO from raw material monomer olefins and other auxiliary gases in the production of ethylene by cracking ethylene to produce polyethylene, and can remove trace oxygen and sulfur. The purification effect is good, and the carbon monoxide content of the purified gas can be up to Below 0.1ppm, the catalyst has the characteristics of long service life, high removal activity, good regeneration effect, and excellent stability, and is well received by users.
