Study on furfural conversion into aromatics over Zn/HZSM-5 and Fe/HZSM-5 catalysts

ZSM-5 zeolite material (Si/Al ratio = 25) was synthesized with silica source of TEOS and TPAOH template. The zeolite is modified into proton form (HZSM-5) with 343 m2 /g of BET surface area, 324 m2 /g of micropore area, 0.1491 cm3 /g of micropore volume and 5.77 nm of BJH adsorption average pore width. Zinc oxide and iron oxide are dispersed onto HZSM-5 catalyst surface with different contents by wet impregnation method. The results of HZSM-5, Zn/HZSM5, Fe/HZSM-5 catalyst materials still retain the micropore structure of ZSM-5 zeolite. These materials are used as catalysts for furfural pyrolysis in the inert atmosphere (N2) with the temperatures ranged from 400 to 700 °C.
