Carbon monoxide oxidation rates computed for automobile exhaust manifold reactor conditions [electronic resource] /

Carbon monoxide oxidation rates have been computed by integrating differential equations for a system of 29 reversible chemical reactions. At temperatures above about 1030 K (1400 degree F) oxidation is rapid and is complete in times short in comparison to the residence times in exhaust manifold reactors. This suggests that such reactors are mixing rate limited, not reaction rate limited. At temperatures below 1030 K rates may be considerably slower. At these lower temperatures the reaction is catalyzed by nitric oxide. Thus, elimination of nitric oxide from automotive exhausts might degrade the low temperature performance of exhaust manifold reactors.Prepared at Lewis Research Center."December 1970."Cover title.Includes bibliographical references (p. 12-13).Carbon monoxide oxidation rates have been computed by integrating differential equations for a system of 29 reversible chemical reactions.
