Abstract: Benzene alkylation with propylene was studied in the gas phase using a catalytic
membrane reactor and a fixed-bed reactor in the temperature range of 200–300 °C and with
a weight hourly space velocity (WHSV) of 51 h−1. β-zeolite was prepared by hydrothermal
synthesis using silica, aluminum metal and TEAOH as precursors. The membrane’s XRD
patterns showed good crystallinity for the β-zeolite film, while scanning electron
