The effect of component

temperature and flow on characteristic of methane/steam/carbon dioxide reforming reaction in the presence of oxygen in micro-annular chamber was numerically simulated using the surface elementary reaction mechanism.The results indicate that the effect of steam on the yields of H2 is obvious but the effect of carbon dioxide is inconspicuous at low temperature.Increasing the content of steam (carbon dioxide) can improve the conversion efficiency of methane.As the temperature rises

the effect of steam (carbon dioxide) component on the characteristic of reforming reaction becomes more obvious.The content of hydrogen (carbon monoxide) and the conversion efficiency of methane at outlets obviously decrease with increasing flow rate.The effect of steam (carbon dioxide) on the conversion efficiency of methane becomes is no longer obvious at high flow rate.As a product of the reaction

the content of steam (carbon dioxide) at outlets maintains unchanged with increasing flow rate.On the contrary

as a reactant of the reaction

the content of steam (carbon dioxide) at outlets increases with increasing flow rate.
