Hydrogenation reactions in dense gas systems

The produced hydrogen from SR is separated through a dense proton-conducting membrane to react with oxygen contained in an air stream. The exothermic reaction between H2 and O2 is used as heat source for ATR of methane. A 10% Ni supported on Y-AI2O3 catalyst is placed on top of the perovskitic membrane. Without the presence of catalysts, methane conversion is quite poor at 850 °C, less than 20%. As nickel supported catalysts is introduced into the system, the methane conversion increases to 88% (thermodynamic equilibrium conversion is around 96%). This phenomenon is related to the low contact time between gas and catalysts, because the gas flow rate used is high. [Pg.70]
