Abstract: A system for removing methane oxidation catalyst (MOC) poisons from an exhaust gas including a methane abatement unit that may receive the exhaust gas having methane (CH4)and the MOC poisons. The methane abatement unit includes a guard bed that may remove the MOC poisons from the exhaust gas and may generate an intermediate exhaust gas having the CH4 and devoid of the MOC poisons. The guard bed includes a MOC poisons capturing component having a first transition metal oxide, an aluminum oxide (Al2O3) support material, and a dolomite-derived support material. The methane abatement unit also includes a MOC bed fluidly coupled to and positioned downstream from the guard bed. The MOC bed includes a MOC and may remove CH4 from the intermediate exhaust gas to generate a treated exhaust gas having less than approximately 200 parts per million volume (ppmv) CH4.

Abstract: A sulfur-resistant, high activity methane oxidation catalyst for use in removing methane from gas streams having a concentration of methane by oxidizing the methane. The methane oxidation catalyst is especially useful in processing gas streams that also have a concentration of a sulfur compound. The sulfur-resistant methane oxidation catalyst includes a unique multi-crystalline zirconia as a support for a platinum component and a ruthenium component. The multi-crystalline zirconia contributes to the excellent properties of the catalyst. The platinum and ruthenium components can be included in the methane oxidation catalyst in a specific weight ratio that also contributes to the enhanced properties of the catalyst. The sulfur-resistant methane oxidation catalyst may also include a chloride component that contributes to enhanced properties of the catalyst.
