Abstract

The Mechanism of n. hexane dehydrocyclization reaction to benzene has beenstudied with pure hydrocarbons and synthetic naphtha feedstock at the operating conditions: T = 400° - 520°C PT = 10 – 30 kg/cm2 and H2/HC = 4-10 mole/mole using a Catatest Unit operated in a continuous system. The results show that n, hexadiene has been formed as a mayor source of the intermediate molecule of the methylcycloamil ion, an optimum metal site activity was observed for a given acid-site of bi-functional reforming catalyst and – 1 (minus one) of the total reaction order of n. hexane dehydrocyclization to benzene.
