Methanation catalyst is used to convert the small amount of CO, CO2 and O2 into inert methane and water to purify synthetic gas or hydrogen. It uses Ni as active component and stable active alumina as the carrier. LF303/LF303R have the characteristics of high activity, strong thermal resistance, high mechanical strength, low bulk density and long service life. They are widely used in ammonia and hydrogen plants.
