Investigation on the Combined Operation of Water Gas Shift and Preferential Oxidation Reactor System on the kW Scale

A 5 kWel water gas shift reactor was integrated with a 5 kWel preferential oxidation reactor for the purposes of reducing the carbon monoxide levels in a reformate exit stream to levels below 100 ppm. The integrated system worked best at partial load with CO concentrations being reduced to 40 ppm at 60% load level and S/C = 3.2.
