A process for purifying a gas stream containing hydrogen and carbon monoxide consisting of one or more catalysed reactions for the selective removal of carbon monoxide from the gas stream wherein a controlled amount of liquid water is introduced into the gas stream prior to some of the catalysed reactions so as to lower the temperature of the gas stream to a predetermined value at which preferential removal of carbon monoxide takes place in the associated catalysed reaction. The catalysed reactions may be selective oxidation, selective methanation or combination thereof. The process of the invention may be operated in combination with a water-gas shift reaction for the reduction of carbon monoxide in the hydrogen-containing gas stream.
