High Temperature Oxidation of Carbon Monoxide and Methane in a Turbulent Flow Reactor

摘要

The high temperature oxidation reactions of carbon monoxide and methane in oxygen-rich atmospheres have been studied in a turbulent flow reactor. Spatial chemical sampling and gas chromatographic analysis techniques were developed for these studies, and the experimental methods are directly extendable to investigations of higher hydrocarbon oxidations. Overall expressions were developed for the carbon monoxide and methane disappearance rates and for the appearance rate of carbon dioxide in the methane-oxygen reaction. These and other data were used to deduce the re;ative importance of several elementary reactions in the oxidation mechanisms. It was concluded that other reactions in addition to hydroxyl attack on methane are important in governing the methane disappearance rate in oxygen-rich, high temperature systems. (Author)
