Question
The dehydrogenation of Methylcyclohexane (M) to produce Toluene (T) is conducted over a Pt/Al 20 3 catalyst using a differentially operated tubular reactor,
and is done in the presence of H 2 to prevent coke formation. It is asked to determine the kinetic parameters of the model for the empirical equation:
a) - = k(P))
b) and also by the mechanism below, considering, in this case, that PT = 1/3 P H2 (atm)
M + 0 → 0M
OM- 07 + 3H2
87 + 0 +T
H2 + 0 + 842
