CO2 reforming of CH4 to the synthesis gas was investigated in a DC pulsed corona discharge with or without the presence of Ni catalyst. It was established that the corona discharge could effectively lower the reaction temperature range of optimum catalytic performance for reforming. The synergy effect could be found in die simultaneous presence of corona discharge and Ni-catalyst for the conversion of methane and carbon dioxide. The synthesis gas yield was enhanced with increasing DC source voltage and resistance time. The higher conversion values were obtained by using Ni-supported on NaX zeolite itself as a catalyst or in conjunction with corona discharge. The obtained synthesis gas was used as a reactant to produce DME under the elevated pressure up to 20 atm, and the effects of reaction conditions and the type of hybrid catalyst were also examined. For the synthesis of DME, Cu/Zn/HY exhibited an efficient catalytic property as compared with more acidic H-Mordenite catalyst.
