油页岩灰渣制备纳米γ-Al2O3的方法研究
Method for Extracting Nano γ -Al2O3 by Oil Shale Ash
摘要
Abstract
A combined process was proposed for the utilization of waste oil shale ash (OS A) in the production of y -A12O3 nanoparticles. The process consisted of two stages, leaching and sintering. The ultrasonic technique followed by a heterogeneous azeotropic distillation process in the presence of polyethylene glycol (PEG) was carried to ensure complete elimination of the residual water in the precipitate. The structural and morphological properties of the calcined nanocrystalline powders were characterized by X-ray diffractometer (XRD), transmission electron microscope (TEM), Brunauer-Emmett-Teller nitrogen-gas adsorption method (BET). The results indicated that the y -A12O3 powder with a uniform particle was well dispersed and the particle size was 20~40nm.关键词
