Abstract

The reaction of n-hexane and 1-hexene has been investigated on unsupported and supported Mo2C catalysts. Pure Mo2C catalyses the dehydrogenation and aromatization of n-hexane at and above 723 K. Benzene was formed with the highest selectivity, ∼65%, at 773–823 K at a conversion of ∼25%. Mo2C also exhibited high activity towards the reaction of n-hexane when it was deposited in a small amount (2–10%) on SiO2. It is assumed that the production of benzene occurs through the formation and subsequent dehydrogenation–cyclization of hexene. Catalysts prepared in situ revealed that the activation and aromatization of hexane and hexene do not require the presence of Mo–O species in the Mo2C.
