HZSM-5 zeolite was modified with levulinic acid produced in situ via glucose hydrolysis, and the catalysts were characterized by X-ray diffraction, X-ray fluorescence spectroscopy, N2 adsorption-desorption, scanning electron microscopy, NH3-temperature programmed desorption, Fourier transform infrared spectroscopy and thermal analysis. The catalytic performance was evaluated in a fixed-bed micro reactor. The results show that the modified HZSM-5 catalyst has a microporous-mesoporous structure based on the retaining complete crystal structure, its acid content and acid strength decrease and the ratio of B acid to L acid increases, which are conducive to improving the catalyst longevity, oil yield and total selectivity of benzene, toluene and xylene (BTX). At 410℃, 0.1 MPa and methanol (WHSV) 2.2 h-1, the longevity of modified HZSM-5 catalyst reaches 174 h, the oil phase yield is 23.84%, and total selectivity of BTX is 61.39%. Compared to the unmodified catalyst, the longevity of modified HZSM-5 catalystis increased by 144 h, oil yield is increased by 7.29%, and total selectivity of BTX is increased by 3.42%.
