中文摘要	A polyaluminium chloride solution with high Al-13 content self-prepared was used as material for preparing the spherical gamma-Al2O3 by the sot-gel and oil-drop method. Polyethylene glycol with different molecular mass was used as surfactant to investigate the effect on property of gamma-Al2O3. The physical property was characterized by Al-27 NMR (nuclear magnetic resonance) spectra, X-ray diffraction, FT-IR (Fourier transform infrared spectroscopy) and TG-DTA (thermogravimetric-differential thermal analysis). The results showed that surface area, pore volume and pore size of gamma-Al2O3 all increased with the increase of polyethylene glycol molecular mass in the experimental research range, and polyethylene glycol 10000 was the most suitable pore forming additive. gamma-Al2O3 with surface area of 339 m(2).g(-1), pore volume of 0.59 cm(3).g(-1) and pore diameter of 6.9 nm were obtained at 450 degrees C.
