FIELD: treatment facilities.
SUBSTANCE: invention may be used for cleaning hydrogen-rich gas mixtures from carbon oxide. The process is divided into two stages, i.e at temperature no less than 90°C and pressure no less than 1 atm. At the first stage cleaning is performed by selective oxidation of carbon oxide by oxygen and/or air. At the second stage cleaning is performed by selective methanation of carbon oxide. According to the other version of invention, selective methanation may be conducted first, and selective oxidation of the residual carbon oxide may be conducted at the end. Copper and cerium oxide system is used as an active component of selective oxidation catalyst, whereas nickel and cerium oxide system is used an active component of selective methanation catalyst.
EFFECT: invention allows for improving effectiveness of hydrogenous gas mixtures cleaning from carbon oxide.
