OP-II-3

OP-II-24of reactant conversions. Parametric studies conducted by variation of plate materialand wall thickness led to minor changes in thermal patterns and indicated nosignificant effects on reactor performance. In contrast, variations in operationalparameters such as water-to-hydrocarbon and oxygen-to-hydrocarbon ratios resultedin notable changes in reactor output. In ethanol steam reforming, water-deficient feedin the reforming channel reduced ethanol conversion and hydrogen productiondramatically. Any reduction in the oxygen content of the total oxidation channelcaused methane conversion values to be significantly lower, leading to lower heatproduction and consumption rates. Dynamic simulations conducted for analyzingreactor start-up behavior showed that the temporal and spatial evolutions oftransients converge to the steady state solution.References[1].
