Dehydrogenation Mechanism and Gas-Phase HO -Dependent Elementary Reactions

1 DEHYDROGENATION MECHANISM AND GAS-PHASE HO -DEPENDENT ELEMENTARY REACTIONS [Pg.147]

Currently, the idea that the HO2 radical plays a key role is the foundation stone in the interpretation of multiple mechanisms for gas-phase oxidation reactions, which may scarcely be explained on the basis of different suggestions. [Pg.147]

For example, in oxidation reactions proceeding at relatively high temperatures mostly as oxidative dehydrogenation and cracking (above 500 °C), HO2 radicals become the main active sites of the substrate radical transformation. As is known, these radicals are produced [Pg.147]

Atomic oxygen formation from H202 at conjugated dehydrogenation of hydrocarbons on the reactor walls is of low probability, but to justify the possibility of oxygen participation in dehydrogenation, nitrous oxide decomposition [3] [Pg.148]

Cyclohexane dehydrogenation in the presence of H202 displays higher selectivity at higher conversion level than in the presence of N20 [5] [Pg.148]
