Features of ignition of mixtures of hydrogen with hydrocarbons (C2, C3 and C5) over rhodium and palladium at pressures of 1–2 atm

It was found that the reactivity of a hydrocarbon during oxidation catalyzed by a noble metal begins to play a significant role with an increase in the number of carbon atoms in its molecule. Thus, the process of hydrocarbon mass transfer to (or on) the catalyst surface determines the oxidation rate.
