Abstract
The parent HZSM-5 was activated by NaOH solution with different concentration to obtain a series of alkaline activated HZSM-5-m (m denotes the concentration of NaOH). Zn (2 wt%) was supported on HZSM-5 and HZSM-5-m via the impregnation method by using Zn(NO3)2·6H2O as a precursor. The materials were systematically characterized by XRD, FT-IR, N2 adsorption–desorption at low temperature, and NH3-TPD techniques. It was found that the acidity and textural properties of the HZSM-5-m could be adjusted by altering the concentration of NaOH. Moreover, the amount and distribution of acidity and the pore structure of catalyst had a significantly influence on heptane conversion and aromatics content. As a result, an efficient Zn/HZSM-5-m catalyst for aromatization reaction was obtained by changing the concentration of NaOH.
