Nitric oxide reduction by carbon monoxide and hydrogen in helium by platinum and ruthenium catalysts supported on fiber glass has been studied. The rate data from a differential tubular reactor operation, at atmospheric pressure and in a temperature range of 200-350 °C, were correlated with a power law model. Feed concentrations for the NO, CO, and H2 were in the range of 0.5-5.0 mol %. N20 was found to be a significant product of reaction at low conversion, but it declined at higher conversions. The relative rates of reaction and the general dependence of reaction rate upon feed concentration and catalyst were in substantial agreement with previous studies with the same reaction system using different supports.
The reduction of nitric and nitrous oxide by mixtures of carbon monoxide and hydrogen in helium over a fiber glass supported Ruthenium catalyst has been studied. The rate data from a differential tubular reactor, operating at atmospheric pressure and at temperatures ranging from 210 to 360 °C, were correlated with power law models. Feed concentrations of the NO and N20 were varied from 0.2 to 1.7 mol %, while those of the CO and H2 were varied from 1.0 to 5.0 mol %. N20 was found to be a significant intermediate product of NO reduction at low conversions. The relative rates of reaction and the dependence of reaction rate upon feed concentration were in general agreement with previous studies of the same reaction systems using different supports.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
