“Compliance with both RICE NESHAP and Opacity Limits is now possible with this catalyst that selectively oxidizes CO, but not NO. Precious metal catalysts are widely used in HAPs converters to reduce CO emissions from IC engines in order to comply with the EPA’s RICE NESHAP regulation. Platinum catalysts also convert the nitric oxide (NO) in the engine exhaust to nitrogen dioxide (NO2), which under certain conditions can produce a visible plume and cause an opacity problem. To solve this dilemma…
