“…In plasma processing, carbon deposit on the walls of the reactor and on electrodes could be a serious problem with a consequence of decreasing the system efficiency (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) . However, one can note that high hydrogen purity can be obtained through that reaction avoiding CO and CO 2 production.…”

Propane steam reforming using a sliding discharge reactor was investigated under atmospheric pressure and low temperature (420 K). Non-thermal plasma steam reforming proceeded efficiently and hydrogen was formed as a main product (H 2 concentration up to 50%). By-products (C 2 -hydrocarbons, methane, carbon dioxide) were measured with concentrations lower than 6%. The mean electrical power injected in the discharge is less than 2 kW. The process efficiency is described in terms of propane conversion rate, steam reforming and cracking selectivity, as well as by-products production. Chemical processes modelling based on classical thermodynamic equilibrium reactor is also proposed. Calculated data fit quiet well experimental results and indicate that the improvement of C 3 H 8 conversion and then H 2 production can be achieved by increasing the gas fraction through the discharge. By improving the reactor design, the non-thermal plasma has a potential for being an effective way for supplying hydrogen or synthesis gas

“…Methane, as the main component of natural gas, is one of the most studied molecules for reforming reactions. However, several studies have been centered on processing and valorizing a number of higher alkanes such as ethane [125,126], propane [127][128][129][130], n-butane [131][132][133] which are present in natural gas, but also generated in engine burners. Among reforming reaction, the steam reforming (SR) of higher alkanes is probably the most common and cost-effective industrial process for H2 generation.…”

Abstract:The treatment of volatile organic compounds (VOC) emissions is a necessity of today. The catalytic treatment has already proven to be environmentally and economically sound technology for the total oxidation of the VOCs. However, in certain cases, it may also become economical to utilize these emissions in some profitable way. Currently, the most common way to utilize the VOC emissions is their use in energy production. However, interesting possibilities are arising from the usage of VOCs in hydrogen and syngas production. Production of chemicals from VOC emissions is still mainly at the research stage. However, few commercial examples exist. This review will summarize the commercially existing VOC utilization possibilities, present the utilization applications that are in the research stage and introduce some novel ideas related to the catalytic utilization possibilities of the VOC emissions. In general, there exist a vast number of possibilities for VOC OPEN ACCESSCatalysts 2015, 5 1093 utilization via different catalytic processes, which creates also a good research potential for the future.

“…Most studies have focused on the steam reforming of propane using supported Ni, Co, Ru and Pd catalysts operated at relatively high temperatures, typically 500-700 • C [15][16][17]. Among these catalysts, noble metals are the more efficient system compared to the transition metals with respect to propane conversion and hydrogen selectivity, probably due to their strong capacity for breaking the C C bond of propane.…”
