increase of H2 conversion. And low concentration of H2 is beneficial for H2 conversion performance due to the
inhibited surface diffusion processes. The reaction rates of H2 on the dependence of temperature at three pres-
sures are given. Results suggest that the effect of temperature becomes more sensitive at high pressure. The
reaction rate of H2 is also higher in high pressure conditions.
