Preferential oxidation reactor integrated with heat exchanger and operating method thereof

A preferential oxidation reactor, comprising:

• a first pipe having an inlet for receiving gas;
• a heat exchanger comprising:
• a plurality of sub-pipes connected to the first pipe;
• a heat transfer plate positioned between the plurality of sub-pipes and having a thin and crimped shape;
• and
• a fan blowing air to the heat transfer plate;
• a second pipe connected to the plurality of sub-pipes and having an outlet;
• a catalyst part positioned in the second pipe, the catalyst part catalyzing a reaction of carbon monoxide contained in the gas;
• and
• a first temperature sensor measuring the temperature of the gas coming out through the catalyst part.
