“…Some models take into account only reaction kinetics while other models are more advanced including also fluid dynamics. Some authors have developed unique models to describe specific plasma techniques such as Thermal Arc [17], DBD [49][50], MW [51], Gliding Arc [52] or DC micro-glow [53] while others have taken into account general conditions and extended the results to describe different discharges [36][54] [55].…”

“…Various methane reforming technologies resulting in different product distributions have been studied: non-oxidative methane coupling, pyrolysis, partial oxidation and dry and steam reforming are of great interest because the formed products have high commercial value. In non-oxidative methane coupling two methane molecules are directly coupled to acetylene and ethylene at high temperatures (>1000°C [17]).…”

Methane is an important raw material for fuel and commodity chemicals production. Energyintensive steam methane catalytic reforming in gas-fired furnaces is the main industrial process for methane conversion to synthesis gas and further to other chemicals. Methane conversion by means of non-thermal plasma technologies has attracted attention in the last years, as no pre-heating of the feedstream at high temperatures is needed. Electric energy is consumed in producing energetic electrons for molecule bonds breaking, instead of gas heating, thereby overcoming the disadvantages of high operational temperatures. In this work, after introducing plasma classification and plasma chemistry, a comprehensive review of literature papers on non-thermal plasma-assisted methane coupling in the period 2010-2016 is presented and the best results that have been obtained with all different kinds of non-thermal plasma techniques are reported. Finally, as the energy cost is the main cost driver of the process after the raw material cost, comparison among all plasma techniques used for methane coupling is performed in terms of specific energy requirement to crack a mole of methane (SER, kJ/molCH4), efficiency (η %) and energy requirement to produce a mole of target product (ER, either kJ/molC2H2 or kJ/molC2H4). This is followed by a comparison between plasma-driven and thermal energy-driven methane coupling.

“…Because of the high transportation costs, parts of the natural gas obtained is re-injected (11%), flared, or vented (4%) at the moment [4]. These problems have led to worldwide efforts to find some solutions in situations where no pipeline transport network is available [5][6][7][8][9].

“…Both methane and CO 2 (which are present in many natural gas resources) are greenhouse gases responsible for global warming, and more strict regulations about letting out or flaring are expected in the future. These problems have led to worldwide efforts to find some solutions in situations where no pipeline transport network is available [5][6][7][8][9].…”

SUMMARY A new and very promising application of auto‐thermal reactors is the coupling of endothermic and exothermic reactions where the product of the endothermic reaction is the desired one. Therefore, in this work, a reactor in which oxidative coupling of methane (OCM) and steam re‐forming of methane (SRM) reactions take place simultaneously was modeled. The results were obtained in a wide range of different conditions such as inlet feed, inlet temperature, portions of OCM and SRM catalysts, and inlet velocity. In selection of the catalysts, more attention was drawn to prevent re‐forming of OCM products. The main parameters of each reaction under different conditions such as conversion of the feed components, products selectivity and yield, temperature in the length of reactor, and component's concentration in the reactor were considered in course of this study. The results revealed that simultaneous OCM and SRM reactions in one reactor will tend to be auto‐thermal, and the waste of energy will be reduced. The results also show that complete conversion of water and majority of methane and oxygen will decrease the amount of unwanted products at the reactor's discharge–a constraint that exists in single reactors of each reaction specially OCM.
