KJ-1 methanation catalyst is a new type of trace CO and CO2 methanation catalyst developed on the basis of high-temperature-resistant coal gas methanation catalyst. This product is suitable for the removal and purification of trace amounts of CO and CO2 in medium and small synthetic ammonia plants or hydrogen production plants. The CO and CO2 in the synthesis gas are reacted with hydrogen under the action of a catalyst to generate methane, so as to protect the ammonia synthesis catalyst from the poison of CO and CO2.
