CH4–CO2 reforming by plasma – challenges and opportunities

Production of CH4 and C2 hydrocarbons by axial and radial pulse H2/CO2 discharges with Ni catalysis

“…However, a little work has been reported for CH 4 production from a mixture gas of CO 2 /H 2 . In most cases, CO 2 was reduced by CH 4 to produce syngas of CO and H 2 , because methane is also one of the greenhouse gases [13][14][15][16][17][18][19][20]. The production of CH 4 was studied by a dielectric barrier discharge with H 2 in detail [5], where mixed gas of CO 2 and H 2 was employed for CH 4 production.…”

Partial oxidation reforming of simulated biogas in gliding arc discharge system

“…In biogas reforming, methane decomposition and boundary reactions (4 and 5) are possible, For biogas, combination of carbon dioxide and partial oxidation of methane can reduce coke deposition on electrodes' surface. Furthermore, application of plasma technology may enable high conversion at reduced energy consumption of the chemical process [8].…”

“…Non-thermal plasma has low electron density (< 10 19 m -3 ) and dissimilarity between electron and heavy particle temperatures. Inelastic collisions between electrodes and heavy particles create the plasma reaction species whereas elastic collisions heat the heavy particle [8,10,11]. Advantage of using non-thermal plasma is associated with lower temperatures, lower energy consumption and electrode erosion [12].…”

Ce - promoted catalyst from hydrotalcites for CO2 reforming of methane: calcination temperature effect

“…[13][14][15] Recently, CO 2 reforming of methane has gained considerable interest because of the global need for the generation of new energy sources to replace oil. From this catalytic reaction, syngas with a H 2 / CO molar ratio close to 1 is obtained, suitable for the production of liquid fuels by Fischer-Tropsch synthesis.…”

“…However, the thermodynamic tendency for coke formation in commercial catalysts have made this process little industrialized. [13][14][15] We have reported the use of different types of hydrotalcites and natural clays as catalyst precursors for CO 2 reforming of methane. [16][17][18][19][20][21][22] Specifically, in our work with hydrotalcites we have focused on the study of hydrotalcites of Ce-containing Ni-Mg-Al obtained by coprecipitation, 19,22 reconstruction 17,18 and self-combustion methods.…”
