Abstract:
Nitrous oxide is one of the trace gases that contribute to greenhouse warming as well as stratospheric ozone depletion. The role of vehicular emissions in the global inventory budget is currently in doubt due to two recent findings: (1) catalytic converters increase the levels of N2O emissions from vehicles, and (2) past measurements are questionable due to the discovery of artifact N2O during collection and due to interference of CO and CO2 during analysis the infrared spectrophotometry (IR). For elimination of CO interferences, the set of methods has been tested, included absorption methods and selective oxidation of CO. As an optimal method for carbon monoxide elimination has been chosen the selective oxidation in specially constructed fixed-bed reactor filled with platinum-based catalyser.
