In this work, the details of catalyst poison deposition are studied, and new catalyst restoration methods are explored. Lubrication oil makes its way through the combustion chamber and into the exhaust system, depositing poisons onto the catalyst and…
Oxidation catalysts are often utilized to reduce carbon monoxide, formaldehyde, and volatile organic compounds in order to meet emissions regulations for large bore natural gas engines. These catalysts degrade over time and need to be replaced or…
Two-way catalysts or oxidation catalysts are the common after-treatment systems used on lean burn natural gas engines to reduce CO, VOCs and formaldehyde emissions. The study evaluates the performance of oxidation catalysts from commercial vendors…
Oxidation catalysts are typically specified to reduce carbon monoxide (CO), Hazardous Air Pollutants (HAPs) and/or Volatile Organic Compounds (VOCs) from lean-burn engines. The application of catalysts to HAPs and VOC destruction is more recent, so…
This study examines the degradation of an exhaust oxidation catalyst on a Cooper-Bessemer GMVH 12C2 gas engine. Critical parameters were determined, such as light-off temperature and reduction efficiency at 450 and 600?F. The catalyst surface was…
