CATALYST, METHOD OF PREPARATION THEREOF, AND A METHOD TREATING HYDROGEN-CONTAINING GAS MIXTURES TO REMOVE CARBON MONOXIDE Russian patent published in 2008 - IPC B01J23/755 B01J23/10 B01J37/02 C07C1/04

Abstract RU 2323044 C1

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.
