摘要: Abstract Aromatics including benzenes, olefins and naphthalenes derived from renewable biomass are of great importance on the potential substitution for diminishing fossil fuels. In this work, aromatics biomass-derived sorbitol by hydrogenation aromatization was investigated over Ni/HZSM-5 Ni/Hβ catalysts in a fixed-bed reactor. The testing results showed that all revealed 100% conversion, while formation carbon species were various during catalytic processing sorbitol. selectivity found to be 53.2% 17.1% Ni/HZSM-5(38) catalyst, respectively. addition, characterized N 2 physical adsorption, X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), H temperature-programmed reduction (H -TPR), desorption ammonia (NH 3 -TPD) techniques. characterization catalyst contained optimum acidic sites structural property, which favor reaction.
