摘要： A low profile two-bed catalytic converter including substantially identical top and bottom housing plates and top and bottom catalyst-retaining plates therebetween which define an inclined catalyst-containing space. A plurality of openings in the retaining plates distribute exhaust flow uniformly through the catalyst-containing space. A partition made up of two spaced plates has a plurality of uniformly distributed exhaust flow apertures therein and extends through the catalyst-containing space to divide the space into upper and lower catalyst beds. An air distribution means between the partition plates has outlet nozzles for discharging air laterally into streams of exhaust gas flowing through apertures in the air distribution means as the exhaust gases pass from the upper to the lower catalyst bed.
