In the present work the process of hydrogen production was conducted in the plasma-catalytic reactor, the substrates were first treated with plasma and then introduced into the catalyst bed. Plasma was produced by a spark discharge. The discharge power ranged from 15 to 46 W. The catalyst was metallic nickel supported on Al2O3. The catalyst was active from a temperature of 400 °C. The substrate flow rate was 1 mol/h of water and 1 mol/h of methanol. The process generated H2, CO, CO2 and CH4. The gas which formed the greatest amount was H2. Its concentration in the gas was ~60%. The conversion of methanol and the production of hydrogen in the plasma-catalytic reactor were higher than in the plasma and catalytic reactors. The synergy effect of the interaction of two environments, i.e., plasma and the catalyst, was observed. The highest hydrogen production was 1.38 mol/h and the highest methanol conversion was 64%. The increased in the discharge power resulted in increasing methanol conversion and hydrogen production.

“…The line integrations were performed through fitting by Lorenz functions (in some cases it was necessary to apply multipeaks fitting), whose results were well correlated to the line profiles, as expected in LIBS plasmas with sufficiently high electron densities. 32,33 The use of the line integrals instead of peak values, together with the normalization to continuum emission intensity, significantly improved the correlation coefficients in the calibration plots shown in Fig. 5.…”

“…The average density of electrons decreases from 10 15 to 10 11 cm -3 with the duration of streamer [36]. The energy of electrons ranged from 0.1 to 4 eV in the spark discharge [36,38]. The maximum temperature of the gas reaches 5000-6000 K in the streamer channel [36].…”

Abstract:The decomposition of CCl 4 in air was investigated at atmospheric pressure in two discharges. Reactors used to generate electrical discharges were powered by the same electric power supply. In both reactors, nearly 90% conversion of CCl 4 was obtained. All chlorine was in the form of Cl 2 in the process carried out in the barrier discharge, while in the spark discharge, COCl 2 was formed. The conversion of CCl 4 to COCl 2 ranged from 2 to 12%. NO was formed in both discharges but the NO content in the gas leaving the reactors was 1.7-2.7% for the spark discharge and 0.045-0.06% for the barrier discharge. O 3 was produced only in the barrier discharge and its content ranged from 0.1 to 0.2%.
