CATALYST, METHOD OF PREPARATION THEREOF, AND A METHOD TREATING HYDROGEN-CONTAINING GAS MIXTURES TO REMOVE CARBON MONOXIDE

摘要

FIELD: catalytic gas treatment. ^ SUBSTANCE: invention proposes catalyst for treating hydrogen-rich gas mixtures to remove carbon monoxide via methanation of carbon monoxide, said catalyst containing nickel-cerium oxide system. Catalyst is prepared by reaction of nickel compounds with cerium compound. Methanation of carbon monoxide is conducted at temperature not below 20°C and pressure not below 0.1 atm in presence of above-indicated catalyst. ^ EFFECT: enhanced removal of carbon monoxide to level below 10 ppm. ^ 8 cl, 5 tbl, 9 ex
