Abstract
An improved apparatus and process for the removal of gaseous impurities from an impure gas stream of hydrogen contaminated with carbon monoxide, and with one or more additional impurities such as carbon dioxide, oxygen, nitrogen, water, methane. The impure gas stream is first contacted with elemental nickel in a first reaction zone under nickel-carbonyl forming conditions thereby converting substantially all the carbon monoxide to nickel carbonyl, thereby producing a partially purified gas stream. The partially purified gas stream is then contacted with Ti.sub.2 Ni or certain manganese-containing alloys in a second reaction zone to produce a fully purified gas stream.
