Silent Electric Discharge in the Equimolar Dihydrogen-Carbon Monoxide Mixture

Article abstract of DOI:10.1246/bcsj.57.869

The purpose of this paper is focused on seeking the posibility of utilizing electric discharge in H2-CO mixtures as a mean of industrial process.Along this line, the silent discharge in the equimolar mixture of CO and H2 has been studied as a function of both the flow rate of reacting gas mixture and the length of the discharge tube.The yield of formalehyde, the main product, increased with increasing flow rate of gas.At a given flow rate, however, the yield increased with increasing tube length indicating that the selectivity of formaldehyde can be increased steadily by increasing the rate of gas flow.The best value of the formaldehyde selectivity was 34percent at the shortest residence time (0.25 s).Improvement of this value seems to be promising.
