The interaction of HZSM5 and Mo-ZSM5 with benzene, naphthalene, toluene, ortho-xylene, pam-xylene, n-butane, isobutane, n-heptane, and methylcyclohexane, in the range 100-773 K has been investigated using FT-IR spectroscopy.

Abstract

The interaction of HZSM5 and Mo-ZSM5 with benzene, naphthalene, toluene, ortho-xylene, pam-xylene, n-butane, isobutane, n-heptane, and methylcyclohexane, in the range 100-773 K has been investigated using FT-IR spectroscopy. Hydrogen bonded species with the internal bridging and the external terminal OHs has been detected. The reactivity at high temperature has also been studied. The access to the internal cavities and to the strongly acidic OHs is at least partly hindered in the case of Mo-ZSM5. The catalytic activity of ZSM5 was moderated by the addition of molybdenum, with lower cracking and higher liquid yields. (C) 2001 Elsevier Science B.V. All rights reserved.
