Abstract
A thermodynamic and kinetic (experimental) study of N2O with CH4 to synthesis gas (H2+CO) formation was investigated under various reaction conditions. The experimental study was carried out over Co-ZSM-5 as catalyst in a fixed bed reactor. The effect of temperature (270 °C -570 °C) and molar feed ratio (N2O/CH4 = 1, 3, and 5) was examined in order to determine conditions for maximizing H2 yield. The results show that for the molar feed ratios (N2O/CH4) of 1 and 3, N2O is the limiting reactant. The thermodynamic and kinetic analyses of the reaction having a limiting N2O reactant in reactant feed (N2O/CH4) shows that H2 yield steadily increased with increase in temperature and the level of CH4 conversion. Furthermore, the maximum attainable (from thermodynamic calculations) H2 yield at 550°C is about 20%. While thermodynamic predictions of H2 yield drops to zero in presence of excess of N2O in reactant feed (N2O/CH4 = 5). Over Co-ZSM-5 catalyst and with a molar reactant feed ratio (N2O/CH4) of 5, the H2 yield first increases to 10 % with rise in temperature and then drops to zero at relatively higher range of temperatures (above 425°C). The synthesis gas production from partial oxidation of CH4 with N2O may not be an alternative route to existing industrial practice; however, the fractional substitution of O2 with N2O in the partial oxidation of CH4 could lead to emission reductions. This will also give a new route for H2 generation.
