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.

“…Another promising method is the use of plasma technology, whether plasma electrocatalysis or using integrated plasma assistedcatalyst [17][18][19][20][21] that had been applied for other synthesis. Over the past decade, non-thermal plasmas have been investigated as a way to catalyze the conversion processes of various hydrocarbon fuels into syngas.…”

Biodiesel synthesis reaction routes from palm oil using plasma electro-catalysis process over Dielectric-Barrier Discharge (DBD) plasma reactor were studied. The study was focused on finding possible reaction mechanism route during plasma electro-catalysis process. The prediction was performed based on the changes of Gas Chromatography Mass Spectrometer (GC-MS) and Fourier Transform Infra Red (FT-IR) analyses to the biodiesel products with respect to time length of plasma treatment. It was found that main reaction mechanism occurred in the plasma electro-catalysis system was non-thermal pyrolysis rather than transesterification. The main reactions within the plasma treatment were due to collision between high energetic electrons (supplied from high voltage power supply through high voltage electrode) and the reaction mixtures. The high energetic electrons affected the electrons pair of covalent bonding to be excited or dissociated even ionized at higher energy. Therefore, this plasma electro-catalysis system was promising for biodiesel synthesis from vegetable oils due to only very short time reaction was needed, even no need a catalyst, no soap formation, and no glycerol by-product. This system could produce fatty acid methyl ester yield of 75.65% at 120 seconds and other possible chemicals, such as alkynes, alkanes, esters, carboxylic acid, and aldehydes. However, during the plasma process, the reaction mechanisms were still difficult to be controlled due the action of available high energetic electrons. The advanced studies on how to control the reaction mechanism selectively in the plasma electro-catalysis will be published elsewhere.

“…A GA system of conversion of hydrocarbon fuel into synthesis gas was first developed with a simple 2-D planar geometry [11], [17]- [20]. The shortcomings of the 2-D reactor, however, included an unsteady discharge due to the high gas velocity and an inefficient mix between the plasma and the feed gas.…”

A new kind of gliding-arc reactor was designed for this study. A shape-memory-alloy electrode controls the discharge arc movement at the start of the discharge stage, while the root of the arc shifts to the ground electrode under normal operation. Experimental results for electrical parameters (voltage and current) in air were analyzed. When the power is adjusted from 50 to 70 W, the discharge waveform is close to sinusoidal at the condition of high power supply. The voltage-versus-current relationship was studied for the Reynolds number (Re number) ranging from 1174 to 2609, current ranging from 20 to 50 mA, and electrode gaps ranging from 11 to 24 mm. There is a linear relationship between root mean square (rms) voltage and the electrode gaps and an inverse linear relationship between rms voltage and rms current.
