Abstract
There are provided an improved thermal reactor apparatus for, and an improved method of, purifying exhaust gases, particularly from a motor vehicle, wherein thermal oxidation and catalytic oxidation of the CO and HC contents of the exhaust gases and/or catalytic reduction of the NO.sub.x contents of the exhaust gases are effected within an environment such that at least some of the components of the reactor exposed to the exhaust gases are coated with and/or made of a catalytic alloy capable of acting as a catalyst for oxidation of the CO and HC contents of the exhaust gases and for reduction of the NO.sub.x contents of the exhaust gases. In the preferable embodiment of the invention, the above mentioned environment comprises an upper stream zone occupied by a rich reducing gas mixture, including the starting exhaust gases, and a lower stream zone occupied by a rich oxidizing gas mixture, including the resultant gases from the upper stream zone and additional air.
