A smoking article and its method of construction and operation to provide products of combustion which are used to form flavorable aerosol gases delivered to the smoker's mouth while controlling the composition of such gases of combustion. Hot gases generated in a catalytic section in which fuel and air combust aided by a honeycomb catalytically coated surface including alumina and a cerium compound.

[ We claim:] [1.] A smoking article with a mouthpiece section and a tip end in which gases flow to the mouthpiece section in a downstream direction with a plurality of sections upstream of said mouthpiece section comprisinga. a heat source portion positioned at the tip end for producing gases of combustion in turn comprising(1) side ventilation holes in the article to serve the heat source portion through which outside air enters;(2) an absorbent fuel reservoir further away from the mouthpiece than the ventilation holes through which such air flows to create an air/fuel mixture;(3) a catalyst combustion section further away from the mouthpiece than the fuel reservoir into which and through which the fuel/air mixture flows as such mixture combusts therein to form combustion gases, which catalyst combustion section includes means for guiding such fuel and air mixture to reverse direction away from the mouthpiece toward the mouthpiece;(4) a downstream conduit associated with the combustion section to deliver the gases of combustion toward the mouthpiece;b. an aerosol section into which and through which the gases of combustion flow to form an aerosol andc. a tobacco section into which the aerosol flows as it moves further downstream toward the mouthpiece section.
