A detailed kinetic study of the alkylation of toluene with methanol on HZSM-8 zeolite was carried out in a fixed bed reactor. The catalyst showed high activity, selectivity, and stability. An attempt has been made to relate the overall changes taking place during the reaction. The experimental data are analyzed, and a reaction mechanism proposed based on the product pattern. The Langmuir-Hinshelwood-Hougen-Watson model with dual-site mechanism was used to derive the rate equation. The unknown parameters in the rate equations are estimated by a nonlinear regression method. The kinetic model based on the proposed reaction mechanism has predicted the conversion values, which are in close agreement with the experimentally observed values.
