Abstract:

The objective of this paper is to study experimentally the characteristics of hydrogen-assisted catalytic oxidation of hydrocarbon. The present work focuses on investigating the effects of hydrogen-assisted catalytic oxidation of methane-air over a metal foam-based monolithic catalyst. The 1%Pd/Al2O3/Fe-Ni foam monolithic catalyst was prepared by wet impregnation. The influence of the addition of H2, mixture flow rate, and of the fuel/air equivalent ratio on the catalytic oxidation characteristics was investigated in a continuous flow fixed-bed reaction system with a quartz tube reactor. The compositions of outlet gas were analyzed online by gas chromatography (Agilent 7890A). The experimental results clearly showed that the addition of hydrogen decreases the conversion of methane, as compared with the methane/air combustion. Moreover, the reaction temperature has a very strong influence on methane conversion. It is also shown that the conversion of methane decreases considerably with increase in the hydrogen percentage of the fuels at a certain value of equivalence ratio. In addition, the conversion of methane decreases distinctly with increase in the equivalence ratio; furthermore, the mixture flow rate has a limited influence on the ignition temperature and burn offtemperature. © 2015 by Begell House, Inc.
