The invention relates to the field of catalytic reaction, in particular to a multifunctional CO preferential oxidation catalyst evaluation system. When the oxygen supply path is closed, the first three-way rotary valve is switched to the lower part, the nitrogen supply path and the hydrogen supply path are opened, and the flow rate is adjusted, so that reduction activation of catalysts in the methanol-water reaction path and the CO recovery reaction unit can be realized; after the methanol-water reaction path is heated to a set temperature, the water-methanol supply path pumps a certain flow of water-methanol liquid into the methanol-water reaction path, and after reforming by the catalyst, generated hydrogen mixed gas can be detected by the gas color analysis path, and the catalytic activity of the catalyst can be evaluated. Hydrogen mixed gas generated by the methanol-water reaction path is introduced into the CO recovery reaction unit, a certain amount of oxygen is introduced through the oxygen supply path
