Plasma-catalytic methane conversion with carbon dioxide in dielectric barrier discharges

Plasma-catalytic dry reforming of methane over γ-Al2O3 supported metal catalysts

“…syngas) are not satisfied in the absence of a catalyst. In addition to the production of syngas, noticeable amounts of C 2 -C 4 and oxygenates were often produced in plasma only processes [19][20][21].…”

“…Up until now, only limited catalysts have been investigated in plasma-catalytic dry reforming processes, including Ni/␥-Al 2 O 3 [3,4,12,13,27], Cu/␥-Al 2 O 3 [12], Ni-Cu/␥-Al 2 O 3 [12], Pd/␥-Al 2 O 3 [19], Ag/␥-Al 2 O 3 [19], La 2 O 3 /␥-Al 2 O 3 [28] and zeolite [21,29]. The exploration of low cost and active catalysts has not been fully satisfied for the plasma-catalytic reforming reaction.…”

A study on CO2 and CH4 conversion to synthesis gas and higher hydrocarbons by the combination of catalysts and dielectric-barrier discharges

“…In recent years, the CO 2 reforming of CH 4 by the combination of a DBD and catalysts was the subject of intensive studies by various research groups. Catalysts that have been investigated in DBDs for CO 2 reforming of CH 4 include various zeolites [27][28][29][30], Ni/␥-Al 2 O 3 [31][32][33][34], Cu/␥-Al 2 O 3 [35], Ni-Cu/␥-Al 2 O 3 [35], Pd/␥-Al 2 O 3 [36], Ag/␥-Al 2 O 3 [36], La 2 O 3 /␥-Al 2 O 3 [37], Ni-La 2 O 3 /Monoliths [38], Ni/Ceramic foam [39], Rh/Ceramic foam [39], and ceramic foams [36,39]. It has been demonstrated that zeolites with faujasite structure (zeolite X, zeolite NaY) are effective catalysts in direct CO 2 reforming of CH 4 to produce synthesis gas and C 5 + hydrocarbons in a DBD reactor [27,29].…”

Methane Incorporation Into Liquid Fuel by Nonequilibrium Plasma Discharges

“…They argue that the major process is formation of CH3 radicals with generation of ethane and ethylene. Sentek et al [2] have tested a number of catalysts in combination with DBD plasma for conversion of methane -CO2 mixtures into higher hydrocarbons and alcohols. Similar studies by Liu et al have been conducted [3]; they demonstrated possibility of generation of liquid fuel using DBD discharge ignited in methane-CO2 mixture.…”

“…Intensive research efforts in the area of direct methane conversion into more valuable liquid hydrocarbons have been made. More recently, plasma chemical conversion of natural gas has been investigated, including generation of syngas and gaseous hydrocarbons [1][2][3][4][5][6][7][8][9][10][11].For example, Wang and Xu [1] have shown that in presence of catalysts, it is possible to achieve more than 60% methane conversion into gaseous C2 hydrocarbons using cold plasma reaction. They argue that the major process is formation of CH3 radicals with generation of ethane and ethylene.…”
