A spectrophotometric study was conducted of the conversion of n-hexane (n-h) on H-ZSM-5 both in a hydrogen atmosphere and in vacuum, in order to detect intermediate compounds determining the process mechanism. Results indicate that strong acidic sites, interacting with n-h at 20 degree with participation of chemisorbed oxygen, are present on the surface of H-ZSM-5. Thermal activation of n-h adsorbed in hydrogen on reduced H-ZSM-5 leads to appearance of an absorption band in the spectrum, assigned to the alkyl carbonium ion. Formation of this ion occurs by interaction of n-h molecules with Broensted acid sites.
