Dehydrocyclization is the catalytic formation of aromatics from alkanes with the release of hydrogen, for example in catalytic reforming
The catalytic formation of toluene from heptane proceeds at two different catalytic centers. Cyclization occurs preferentially at the acid centers, and dehydrogenation reactions occur at the metal centers.
Cyclization of n-heptane to methylcyclohexane and 1,2-dimethylcyclopentane, respectively
Dehydrogenation of methylcyclohexane to toluene
The overall reaction is as follows
