Alkylation of benzene over new modified ZSM-5 catalysts with Nd has been done in a metallic tubular reactor. The catalyst was synthesized from components modified with NdCl3 characterized by XR-Fluorescence Spectrometer, XRD apparatus, nitrogen adsorption analyzer and TGA for its acidity. The alkylation experiments have been done at different reaction temperatures, pressures and benzene (ethylbenzene)/bioethanol molar ratio in order to establish their influence on the final composition of the reaction product, selectivity and conversion. The results obtained with Nd modified catalyst were compared with those obtained from unmodified catalyst.
