Non-catalytic plasma-arc reforming of natural gas with carbon dioxide as the oxidizing agent for the production of synthesis gas or hydrogen

Ethylene epoxidation in a low-temperature parallel plate dielectric barrier discharge system with two frosted glass plates

“…The configuration of electrodes was found to influence the efficiency of EO production in that a cylindrical DBD provided superior ethylene epoxidation performance as compared to a parallel plate DBD [7]. The input power, voltage, and electrode gap distance significantly affected the performance of methane reforming [11,12,[30][31][32], corresponding to the study that the dielectric material and thickness changed the plasma behavior [33].…”

“…Therefore, a search for a new method with lower energy consumption, a lower reaction temperature and without the use of a catalyst is of great interest. Non-thermal plasma has been reported to be an alternative technique for several reactions including ethylene epoxidation [7,8], natural gas reforming (H 2 production) [9][10][11][12][13], chemical vapor deposition [14][15][16][17][18][19][20][21], and desulfurization [22,23].…”

Experimental investigation of a non-catalytic cold plasma water-gas shift reaction

“…Industrial systems meet these two opposing requirements using multiple catalytic reactors arranged in series [14][15][16][17]. The catalytic systems have their own challenges, specificallly: the catalysts used are pyrophoric in nature, very sensitive to contaminants present in the incoming gas, are known to facilitate unwanted side reactions such as the formation of CH 4 [18][19][20], get deactivated if exposed to air and/or condensed water and require high temperatures for activation [21,22]. Given these challenges, namely, (i) the additional energy demand for conditioning the gas between shift reactors and (ii) the associated steps of handling/working with shift catalysts, there is a constant search for new processes for achieving the WGS reaction without the use of catalysts.…”

The Effect of Sc Promoter on the Performance of Co/TiO2–P25 Catalyst in Dry Reforming of Methane

“…5,9,10 However, according to the recent scenario of global warming, dry reforming of methane (DRM) has attracted special attentions in comparison to other reforming processes, because this process not only utilizes and/or mitigates two undesirable greenhouse gases (i.e., CO 2 and CH 4 ) but also produces syngas (a mixture of CO and H 2 ) with more preferable H 2 /CO molar ratios for production of valuable synthetic liquid hydrocarbons and oxygenated chemicals through Oxo-and Fischer-Tropsch synthesis processes. [11][12][13] In addition, DRM is also practically applicable and feasible for other hydrocarbons, which have very high content of methane and carbon dioxide such as biogas, a renewable resource consisting of CH 4 (40-70%) and CO 2 (30-60%).…”

“…On the basis of industrial practice, methane reforming processes can be classified into three major processes: steam reforming, dry/CO 2 reforming, and partial oxidation . However, according to the recent scenario of global warming, dry reforming of methane (DRM) has attracted special attentions in comparison to other reforming processes, because this process not only utilizes and/or mitigates two undesirable greenhouse gases ( i.e ., CO 2 and CH 4 ) but also produces syngas (a mixture of CO and H 2 ) with more preferable H 2 /CO molar ratios for production of valuable synthetic liquid hydrocarbons and oxygenated chemicals through Oxo‐ and Fischer‐Tropsch synthesis processes .…”
