Intentional oxygen oscillations on Pd/Al2O3 for enhanced methane removal from the exhaust of natural gas engines

Maneka Claire Roger

Natural gas (NG) is a suitable alternative to gasoline and diesel fuels to decrease the carbon footprint of the mobility and energy sectors. Although NG is considered a fossil fuel, methane (CH4), its main component, can be produced industrially from power ...
