Oxidation catalyst degradation in the exhaust stream of a large bore 2-stroke natural gas engine
Lean burn 2-stroke natural gas engines are commonly used for power generation and gas compression. These engines, however, contribute to air pollution primarily through emissions of carbon monoxide, volatile organic compounds and some unburned hydrocarbons. Oxidation catalysts aid in reducing these harmful emissions. Lubrication oil carryover to engine exhaust degrades the oxidation catalyst making it less effective at reducing emissions. This work combines laboratory and field testing of an oxidative catalyst designed for lean burn natural gas engines. Catalyst performance is tracked over ...
