“…Fundamental physics and chemistry in DBDs is well understood in relation to ozone synthesis and gas cleaning. More recently, DBDs and their combination with solid catalysts are recognized as viable material conversion technology at low temperature, and investigated in steam reforming [16][17][18][19][20][21], partial oxidation [22][23][24][25][26][27], and dry reforming [28][29][30][31][32][33][34][35][36] of hydrocarbon fuels. As for non-thermal plasma assisted dry reforming, carbon deposition and deactivation of catalysts cause serious problem.…”

“…These species are responsible for triggering fuel conversion at low temperatures. Steam reforming of methane [10][11][12]25,26], diesel [27], E85 [28,29], gasoline [30] and propane [31] by DBD have been studied. More recently, CO 2 (dry) methane reforming using non-thermal plasma has attracted keen attention [6] as an important part of carbon capture and utilization (CCU) technology.…”

This paper focuses on reforming dodecane and hydroprocessed renewable diesel to hydrogen rich gas in a non-thermal gliding-arc plasma stabilized in a reverse vortex flow reformer. The liquid fuels were directly injected into the reaction chamber using an ultrasonic nozzle and entrained in the reverse vortex flow before passing through the plasma. Initial parametric tests were used to investigate the individual effects of varying power input, steam to carbon ratio, and equivalence ratio on reformer performance. Subsequent factorial tests varied these parameters to identify optimal specific energy requirements. Optimal reforming conditions for dodecane, a model diesel compound, resulted in specific energy requirements of 134.1 ± 1.1 kJ mol -1 H 2 produced, a H 2 yield of 65.0 ± 0.02%, and an efficiency of 37.0 ± 0.02%. Optimal conditions for hydroprocessed renewable diesel resulted in a specific energy requirement of 176.1 ± 3.8 kJ mol -1 H 2 produced, a H 2 yield of 64.2 ± 1.7%, and an efficiency of 35.0 ± 1.0% at 95% confidence intervals. Physical operating boundaries due to arc extinction were identified. KeywordsNon-thermal plasma, gliding arc reformer, reverse vortex flow reformer, dodecane, hydroprocessed renewable diesel, HRD-76, hydrogen production 1.Recently, the alternative energy sector has experienced rapid growth because of increasing pressure from climate change awareness, rising fuel costs, and a need for domestic energy security [1,2]. New technologies have focused on producing energy that is accessible, environmental friendly, sustainable, secure, and can meet current and future projected energy needs [3]. Hydrogen is expected to play a large role in the energy economy of the future as it can be utilized in fuel cell applications, and in the synthesis of alternative fuels [1,3,4]. This paper explores the use of a non-thermal reverse vortex flow (RVF) gliding-arc reformer for liquid fuels. Tests were conducted using dodecane as a model diesel compound and hydroprocessed renewable diesel fuel. Parametric tests determined the effects of various system parameters, while factorial tests were utilized for system optimization. Current fuel reforming technologies© 2015. This manuscript version is made available under the Elsevier user licenseHydrogen is expected to be a prominent fuel in the future [1,3,4]. However current production methods are expensive, require complex and large machinery or costly catalysts, and require an expensive distribution infrastructure [1,3,5]. Steam, partial oxidation, and autothermal reforming constitute the major reforming technologies [2,3]. Hydrogen production via steam reforming of natural gas utilizes roughly one third of the fuel to support the parasitic energy requirement of the process. Ultimately this leads to an specific energy requirement (SER) of 325 to 354 kJ mol -1 of hydrogen produced [6,7].Since the late 90's, interest in plasma reforming has grown [8]. Plasma reformers can operate in thermal equilibrium or non-thermal equilibrium. Thermal plasma reformers ope...
