文摘
- •
Methane kinetically inhibits catalytic combustion of hydrogen.
- •
A minimum hydrogen composition for methane self-ignition is relatively constant.
- •
The critical point from thermal effect to kinetic effect is found.
- •
Hydrogen promotes methane combustion because of the increase in free Pt(s) sites.
- •
Richer hydrogen composition or lower temperature enhances the kinetic effect.
