Aftertreatment system for the control of emissions in stationary rich burn engines

摘要

A catalyst system (100,111) may include a three-way catalyst (120) that may receive exhaust gases from an engine (110) and convert the exhaust gases to first converted exhaust gases. An ammonia slip catalyst (130) may receive the first converted exhaust gases and convert the first converted exhaust gases to second converted exhaust gases. A hydrocarbon oxidation catalyst (140) may receive the second converted exhaust gases and convert the second converted exhaust gases to third converted exhaust gases.
