废铝基/钯催化剂碱性浸出废液制备拟薄水铝石的研究
Study on the Preparation of Pseudoboehmite Using the Alkaline Leachate of Aluminum Base/Palladium Catalysts
摘要
Abstract
The properties and microstructure of pseudoboehmite prepared by the alkaline leachate of aluminum base/palladium catalysts using sodium aluminate-CO2neutralization method at different conditions were studied. The results indicated that the granular appearance of pseudoboehmite was determined by the terminal reaction pH and aging temperature,while the particle size was charac-terized by the final pH,aging temperature and aging time. Under the conditions of pH=10.5,ag-ing temperature of 90 ℃ and aging time of 4 h,the pure pseudoboehmite product with specific sur-face area of 282 m2/g and dispersion index of 96.2% can be obtained.关键词
