The gases are passed through carbonaceous material, e.g., pyrocarbon, coal, and coke, impregnated with catalytic metal compds. at 0.5-20.0 wt.%. The degree of removal is increased when the carbonaceous material, before the impregnation, is mech. activated in a grinder-activator for 5-30 min in an inert gas.
