Abstract: The present invention provides a method for the destruction of hazardous carbonaceous wastes by the plug flow, thermal combustion of said wastes comprising (a) obtaining an intimate admixture of vaporized fuel and air, said admixture containing at least a stoichiometric amount of air, (b) passing said admixture to a plug flow combustion zone, and (c) effecting sustained and essentially complete combustion of said fuel under essentially adiabatic conditions to destroy said wastes and to form a combustion effluent of high thermal energy; said combustion being characterized by said fuel-air mixture having an adiabatic flame temperature such that that actual flame temperature in the combustion zone is greater than about 1350K.

Abstract: An improved catalytic reactor includes a housing having a plate positioned therein defining a first zone and a second zone, and a plurality of conduits fabricated from a heat conducting material and adapted for conducting a fluid therethrough. The conduits are positioned within the housing such that the conduit exterior surfaces and the housing interior surface within the second zone define a first flow path while the conduit interior surfaces define a second flow path through the second zone and not in fluid communication with the first flow path. The conduit exits define a second flow path exit, the conduit exits and the first flow path exit being proximately located and interspersed. The conduits define at least one expanded section that contacts adjacent conduits thereby spacing the conduits within the second zone and forming first flow path exit flow orifices having an aggregate exit area greater than a defined percent of the housing exit plane area. Lastly, at least a portion of the first flow path defines a catalytically active surface.

Abstract: An emissions control system for rich-burn internal combustion engines, includes a reaction chamber (7) for thermal oxidation of exhaust gas fuel values. A passive means (5, 4) utilizes exhaust flow energy (2) for induction of air into engine exhaust gas, and a duct (3) transfers the exhaust gas together with the inducted air into the reaction chamber (7) for thermal oxidation. To achieve a high degree of efficiency the thermal oxidation is facilitated by thorough mixing of air and exhaust gas by recirculation means (9) to insure gas phase thermal reaction.
