Abstract
1509974 Oxidizing nitric oxide; purifying waste gases MITSUBISHI JUKOGYO KK 11 Aug 1975 [21 Aug 1974 6 Nov 1974] 33425/75 Heading C1A Nitric oxide is converted to NO 2 by reacting the NO with nitric acid vapour in the presence of a porous absorbent catalyst selected from silica gel, "colloid earth", alumina or a natural or synthetic zeolite. The process may be used for removing NO from an NO-containing gas by converting the NO to NO 2 and then absorbing the NO 2 and any SO 2 present in water or an aqueous solution of ammonia, an alkali metal hydroxide or an alkali metal or alkaline earth metal salt of a sulphite, bisulphite or a thiosulphite or mixtures thereof. "Colloid earth" is a naturally occurring material having the formula
