Effect of Polyethylene Glycol Additive on Structure and Performance of Active Alumina by Reverse Precipitation Method

Abstract:

Active alumina (γ-Al₂O₃) was prepared from NaAlO₂ and HNO₃ by a reverse precipitation method with addition of polyethylene glycol (PEG). The effect of PEG additived in the different stages during the preparing process was investigated by powder X-ray diffraction (XRD), fourier transform infrared analysis (FTIR) and nitrogen adsorption-desorption. It was found that the mesoporous alumina sample with the PEG additived into the initial HNO₃ solution was the most effective at improving the surface area and the pore volume of γ-Al₂O₃.
