“…Then, the above intermediates are converted into H 2 , HCHO, HCOOH, and HCOOCH 3 along with other species by the plasma jets as per the following reactions (Eqs. (4), (5), (6), (7), (8), (9), (10), (11), (12), (13), and 14) [56,57,58,59]. But, we have not detected any such species like HCHO, HCOOH and CO 2 in our experiment.…”

“…Hydrogen is a promising option for energy supply and termed as clean fuel having high energy per unit mass [8,9,10]. On combustion, it can produce high thermal energy which is three times higher than that of petrol [11]. In the present day, this is an ideal energy carrier to be used in the petrochemical, automobile and chemical industry sectors [12].…”

In this work, methanol decomposition method has been discussed for the production of hydrogen gas with the application of plasma. A simple dielectric barrier discharge (DBD) plasma reactor was designed for this purpose with two types of electrode. The DBD plasma reactor was experimented by substituting one of the metal electrodes with feebly conducting sea water which yielded better efficiency in producing hydrogen gas. Experimental parameters such as; discharge voltage and time were varied by maintaining a discharge gap of 1.5 mm and the plasma discharge characteristics were studied. Filamentary type micro-discharges were found to be formed which was observed as numerous streamer clusters in the current waveform. Gas chromatographic study confirmed the production of hydrogen gas with residence time around 3.6 min. Although, the concentration (%) of H 2 was high (98.1 %) and consistent with copper electrode assembly, the rate of formation and concentration was found to be the highest (98.7 %) for water electrode for specific discharge voltage. The energy efficiency was found to be 0.5 mol H 2 /kWh and 1.2 mol H 2 /kWh for metal (Cu) and water electrodes respectively. The electrode material significantly affects the plasma condition and hence the rate of hydrogen production. Compositional analysis of the water used as electrode showed a minimal change in the composition even after the completion of the experiment as compared to the untreated water. Methanol degradation study shows the presence of untreated methanol in the residue of the plasma reactor which has been confirmed from the absorption spectra.

“…In a recent study, dielectric barrier discharge (DBD), the electrical discharge between two electrodes separated by an insulating dielectric barrier, was used for the generation of hydrogen from ethanol reforming [10]. It was found that the increase of ethanol flow rate decreased ethanol conversion efficiency and hydrogen yield, and high water/ethanol ratio and addition of oxygen were advantageous for hydrogen production.…”

The purpose of this study is to efficiently produce hydrogen gas from saccharide using 27.12 MHz radiofrequency (RF) in-liquid plasma with and without ultrasonic irradiation. The experiments were conducted adopting two different ultrasonic frequencies, one from a 29 kHz horn-type ultrasonic transducer and the other from a 1.6 MHz piezoelectric transducer. The glucose solution and cellulose suspension concentrations were varied from 0.5 wt% to 50 wt% and 0.5 wt% to 20 wt% respectively. Hydrogen gas was then produced by the decomposition of the glucose solution and cellulose suspension by RF in-liquid plasma with and without ultrasonic irradiation. The hydrogen production rate from glucose solution with ultrasonic irradiation applied was greater than that without ultrasonic irradiation. However, no hydrogen production rate enhancement was observed from decomposition of cellulose suspension with ultrasonic irradiation applied. Ultrasonic atomization and agitation enhanced the chemical reaction of nonvolatile glucose in in-liquid plasma. The increase of the gas production rate was caused by the direct decomposition of the glucose by the plasma due to the atomized glucose molecules being fed into the plasma in a bubble. In addition, by using a high-speed camera, it was clarified that acoustic streaming occurred when a 1.6 MHz piezoelectric transducer was used in the experiment.
