چکیده انگلیسی
Synthesis gas (a mixture of CO and H2) oxidation is studied over a supported Pt/Al2O3 catalyst in a novel microreactor fabricated for studying the intrinsic chemical kinetics of highly exothermic reactions. CO was found to significantly inhibit H2 oxidation. In contrast, H2 addition promotes CO oxidation at low mole fractions but has a small promoting effect at high hydrogen mole fractions. As a result, the apparent reaction order of H2 changes from positive to zero. The change in hydrogen reaction order is associated with hysteresis. Possible mechanisms for the observed behavior are discussed.
