| Abstract: | The conversion of CO

and (CH
4+CO

) mixtures to CO, at room temperature and atmospheric pressure conditions, in pulsed corona discharges, was investigated. Conversion of pure CO
2
was 16.8% at 10 cm

rate of conversion. The CO
2
conversion was improved to 38% (85 mol-min

by feeding the reactor with CH
4+CO

gas mixture (1:1 ratio), simultaneously with CH
