英文摘要: The ERB-1 zeolite was synthesized using silica aerogel as the silica source, boric acid as the boron source, and sodium hydroxide as the alkali source, respectively. The obtained ERB-1 zeolite was characterized by X-ray diffraction (XRD), N-2 adsorption, NH3 temperature-programmed desorption (NH3-TPD), thermogravimetry analysis (TG), differential thermal analysis (DTA) and Fourier-transform infrared reflectance spectroscopy (FT-IR). It was found that the suitable synthesis gel compositions were n(SiO2)/n(B2O3) = 0.6 similar to 2, n(H2O)/n(SiO2) = 40, n(NaOH)/n(SiO2) = 0.1 similar to 0.2, and n(HMI)/n (SiO2) = 0.8 similar to 1. The FT-IR result indicated that a part of boron atoms had incorporated into the framework of ERB-1 zeolite. The TG, DTA, and XRD results showed that the ERB-1 zeolite maintained its framework below 800 degrees C when it was calcined in air flow. The NH3-TPD result exhibited that the ERB-1 zeolite had poor acidity and the weak acid was in the majority of its acid sites.
