The JT-201 hydrogenation catalyst can be widely used in the hydrogenation conversion of olefins and oxygen in carbon monoxide-rich industrial tail gas such as acetylene tail gas from natural gas to acetylene, calcium carbide furnace gas and coke oven gas. At the same time, it has high hydrogenation conversion ability for impurities such as ethylene and oxygen in the gas. The catalyst is also suitable for removing oxygen from hydrogen and nitrogen. It has the characteristics of wide adaptability, high purification degree, and wide operating temperature range. This product has been successfully used in many domestic methanol synthesis plants.
