The catalytic efficiency of Ru/Mn/Ce-Al2O3in the reduction of HCN in dry methane reforming with CO2assisted by non-thermal plasma.
This study investigates the catalytic activity of Ru/Mn/Ce-Al2O3 in eliminating HCN via dry reforming CH4 with CO2 in the packed-bed dielectric barrier discharge non-thermal plasma (DBD NTP). A packed bed DBD configuration method was carried out in the non-thermal plasma with Ru/Mn/Ce-Al2O3 catalyst...

| Summary: | This study investigates the catalytic activity of Ru/Mn/Ce-Al2O3 in eliminating HCN via dry reforming CH4 with CO2 in the packed-bed dielectric barrier discharge non-thermal plasma (DBD NTP). A packed bed DBD configuration method was carried out in the non-thermal plasma with Ru/Mn/Ce-Al2O3 catalyst, whereby BaTiO3 beads was the dielectric medium. The carrier gas for dry methane reforming was N2, the peak-to-peak voltage was 24 kV and the total flow rate was 100 sccm with a ratio of 5:5:90 (CH4:CO2:N2), respectively. Gaseous products and by-products were analysed by Fourier transform infra-red (FTIR) spectroscopy. Experimental results revealed that Ru/Mn/Ce-Al2O3 catalyst could eliminate HCN at approximately 82% and had a low selectivity in decomposing NH3. Besides, the conversion of CH4 achieved was approximately 68%. |
