A catalytic muffler having at least one reactor bed (20, 22) each bed having an array of discreet adjacent flow zones (30, 32, 34, 36). The flow zones ar e interconnected by a series of passages (50, 52, 54) for unidirectional flow (90) of a gaseous fluid sequentially through each adjacent zone (30, 32, 34, 36) in turn from an inlet side of each reactor bed (42) to an outlet side of the reactor bed (44). An inlet (72) fluidly communications with a first of t he flow zones (30). An outlet (74) fluidly communicates with the last of the fl ow zones (36).
