ABSTRACT:
A reactor that can be attached to the exhaust manifold of an internal combustion engine to oxidize and burn carbon soot particles, carbon monoxide, and unburned hydrocarbons, and to dissociate nitrogen and sulfur oxides. The reactor has a reaction zone that contains porous heat-retaining foam cells and that is bounded by a porous heat-retaining zone, which in turn is surrounded by ceramic insulation materials to minimize energy losses. Engine exhaust at elevated temperatures and containing some oxygen (air) enters the reaction chamber. By means of impinging heat transfer, thermal radiation enhancement, energy trapping and combustion of engine emissions, temperatures sufficient to oxidize carbon soot particles, carbon monoxide, and unburned hydrocarbons are attained. Steam or atomized water droplets are introduced to improve the efficiency of the reactor through gasification, regasification, water shift reactions, methanation, and hydrocracking reactions. Harmless product of the oxidation reactions, H.sub.2 O and CO.sub.2, are released from the reactor.
