Slide 4 - Toluene Formation Increased by Surface Hydrogen Reduction |
|
| In order to explore the competition between condensation and hydrogenolysis, the surface was predosed with either hydrogen or oxygen. Hydrogen predosing lowers toluene formation by 25%. Oxygen causes a reduction of free surface hydrogen by reaction to form water below the toluene desorption temperature. This causes a dramatic increase in toluene formation, with a twenty times increase in desorbing toluene. |
