ABSTRACT: Electric discharge
has been carried out in LPG using DC high voltage (0.4 - 3 KV) at gas pressure in
the range of 1 to 25 torr. The electric and spectroscopic characteristics of the
discharge were studied at different discharge conditions. Deviations from Paschen’s
law were observed as a result of the change of the distance between the two the
electrodes. Two discharge modes, namely glow discharge and spark discharge modes,
has been observed in the discharge current waveforms. The discharge current waveforms
indicate a repetitive pulsed behaviour with frequencies of 5 kHz to 5 MHz depending
upon the applied voltage and the gas pressure. The emitted spectra from the discharge
are also studied near both the cathode and the anode using different electrode materials. Hα line and C2 Swan band system
are observed, which confirms the conversion of LPG to hydrogen and carbon clusters.
