Gas chromatographic determination of gases formed in catalytic reduction of nitric oxide
The construction and performance are described of a gas chromatographic system for the analysis of gas mixtures formed during the catalytic reduction of NO with CO, H/sub 2/, and NH/sub 3/. Reactants and products are separated by using three packed columns contained within two isothermally operated gas chromatographs. The system operation, data acquisition, and data reduction are accomplished by means of a microprocessor. Quantitative analysis of NO, NH/sub 3/, N/sub 2/, N/sub 2/O, CO, and CO/sub 2/ can be obtained down to levels in the range of 10 to 35 ppM, and H/sub 2/ can be analyzed down to 400 ppM. Water present in the sample is separated from the other components but is not quantified.
