Microstructured reactors on the 5 kW scale for the water gas shift and preferential oxidation reactions using surrogate diesel reformate

5 kWel One-Stage Water Gas Shift (WGS) and Preferential Oxidation (PROx) reactors were designed and evaluated for the clean-up of surrogate diesel reformate. For the WGS reactor, CO conversions of up to 95% were attained using typical surrogate synthetic diesel reformate. The PROx reactor was capable of converting a feed concentration of 1.0 mol% CO to 20 ppm. The two reactors were then integrated for the purposes of reducing the carbon monoxide levels in a reformate exit stream to levels below 100 ppm.
