Alkylation of toluene with ethylene over H-ZSM-5 catalyst was carried out in a fixed-bed differential reactor at 300-330℃ under atmospheric pressure. A typical Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic expression was postulated, and the kinetic parameters were estimated by a nonlinear regression method. The results of model discrimination by using initial rate and thermodynamic criteria indicate that a noncompetitive adsorption model with surface reaction control scheme is the most suitable one for this reaction.
