Abstract
m-Xylene gaseous phase isomerization over Fe-substituted HZSM zeolite catalyst was studied in a fixed bed continuous laboratory scale reacto r. To investigate the mechanism of transformations laking place on the inner surface of the catalyst, several experiments were carried. out in the presence of pyridine. The isomerization kinetics, including the catalyst deactivation by coke deposition were experimentally and theo retically examined, A kinetic model is formulated and its parameters e stimated for isothermal conditions at 673 K.
