Title: Effects of solution volume on hydrogen production by pulsed spark discharge in ethanol solution

Abstract

Hydrogen production from ethanol solution (ethanol/water) by pulsed spark discharge was optimized by varying the volume of ethanol solution (liquid volume). Hydrogen yield was initially increased and then decreased with the increase in solution volume, which achieved 1.5 l/min with a solution volume of 500 ml. The characteristics of pulsed spark discharge were studied in this work; the results showed that the intensity of peak current, the rate of current rise, and energy efficiency of hydrogen production can be changed by varying the volume of ethanol solution. Meanwhile, the mechanism analysis of hydrogen production was accomplished by monitoring the process of hydrogen production and the state of free radicals. The analysis showed that decreasing the retention time of gas production and properly increasing the volume of ethanol solution can enhance the hydrogen yield. Through this research, a high-yield and large-scale method of hydrogen production can be achieved, which is more suitable for industrial application.

  • In this paper we demonstrate a new concept in the production of negative hydrogen ions in a low-pressure multicusp discharge. The discharge voltage is modulated to produce a non-Maxwellian, hot-electron plasma during the current pulse, followed by a cool Maxwellian electron plasma in the post discharge. This procedure, of separating in time the required hot and cold electron plasmas required for volume H{sup {minus}} production, is called a temporal filter. The time evolution of the electron energy distribution function is measured using the time-resolved second derivative of a Langmuir probe characteristic. Time-resolved measurements of the negative ion density are mademore » using laser photodetachment. The measurements show that the negative ion density in the center of the source, at a gas pressure of 0.07 Pa, increases by a factor of 2 when the discharge is switched off. At this low pressure the average H{sup {minus}} beam current extracted from the source, when operated with a discharge current of 1 A in the pulse modulated mode exceeds the H{sup {minus}} beam current from a 5 A continuously operated source. The increase in efficiency of the pulsed source is explained in terms of a two-step H{sup {minus}} production mechanism.« less
  • The work is dedicated to the theoretical and experimental investigation of the intense H- volume-plasma generation in cesium-hydrogen discharge. A low-voltage (LV) mode of the discharge, a LV arc with a heated cathode, is studied. Theory of the discharge was created. It was shown theoretically that a very high H- density ({approx}1013 cm-3) may be achieved in the discharge plasma. A comparison between the discharge theory and the experiments was fulfilled. The main plasma parameters were measured by probe method. The H- density in plasma was determined from the experimentally measured absorption of laser radiation due to the photodetachment ofmore » electrons from H- ions. The existence of a very high H- density in plasma ({approx}1013 cm-3) was proved experimentally. Theoretical modeling shows that, with a high electron emission from the cathode ({approx}10 A/cm2), the maximum H- density is located in the plasma near the anode. It allows extraction of narrow and bright H- beam through a small opening in the anode.« less
  • The authors have quantified the effect of pressure scaling on Ar metastable production efficiency in a dielectric barrier discharge with and without dielectric component losses. Estimates of the volume averaged deposited energy were performed for both short or long rise time voltage pulses, using the same total applied voltages of {approx}10 and {approx}150 ns, respectively. The metastable production efficiencies of long-pulse discharge exhibit smaller decrease over the 100-500 Torr pressure range, compared to those of the short-pulse one to the extent that the efficiency values and scaling for both cases are essentially the same within the experimental uncertainty.
  • The two-dimensional model of low-pressure discharges presented in the study provides description of hydrogen discharge maintenance in a free-fall regime with account for the volume produced negative ions in the discharge. The factors determining the spatial distribution of the plasma parameters, including that of the negative ions, in discharges with a localized rf power deposition and, respectively, with regions with remote plasma maintenance, are discussed. In agreement with previous one-dimensional models of hydrogen discharges maintained in a free-fall regime, the results show that small radius discharges sustain high density of volume-produced negative ions in the discharge center. This accumulation ofmore » the negative ions in the central part of the discharge where the rf power deposition is localized results from substantial influx of negative ions produced all over the discharge volume, i.e. from a nonlocal behavior of the discharge strongly predominating over the local balance of the ions associated with the elementary processes (collisions).« less
  • In a volume-produced negative hydrogen ion source, control of electron temperature is essential due to its close correlation with the generation of highly vibrationally excited hydrogen molecules in the heating region as well as the generation of negative hydrogen ions by dissociative attachment in the extraction region. In this study, geometric effects of the cylindrical discharge chamber on negative ion generation via electron temperature changes are investigated in two discharge chambers with different lengths of 7.5 cm and 11 cm. Measurements with a radio-frequency-compensated Langmuir probe show that the electron temperature in the heating region is significantly increased by reducingmore » the length of the discharge chamber due to the reduced effective plasma size. A particle balance model which is modified to consider the effects of discharge chamber configuration on the plasma parameters explains the variation of the electron temperature with the chamber geometry and gas pressure quite well. Accordingly, H{sup −} ion density measurement with laser photo-detachment in the short chamber shows a few times increase compared to the longer one at the same heating power depending on gas pressure. However, the increase drops significantly as operating gas pressure decreases, indicating increased electron temperatures in the extraction region degrade dissociative attachment significantly especially in the low pressure regime. It is concluded that the increase of electron temperature by adjusting the discharge chamber geometry is efficient to increase H{sup −} ion production as long as low electron temperatures are maintained in the extraction region in volume-produced negative hydrogen ion sources.« less
