摘　　要：综述了生产活性氧化铝的原料、活性氧化铝的主要制备方法及其改性方法。快脱粉通过快速煅烧α-三水铝石生产;拟薄水铝石通过碳化法、碱法、酸法、中和法和醇铝法生产。快脱粉通过滚动成型制造活性氧化铝球;拟薄水铝石通过油-氨柱成型、挤出成型和喷雾干燥成型制成(条形、三叶草形、蝶形等)不同形状的活性氧化铝。最后,综述了活性氧化铝的几种改性方法,每种方法都可以改进活性氧化铝的物化性能。Raw materials, main preparation methods, and modification methods of activated alumina are summarized. FCA is produced by flash calcination of gibbsite, and pseudo-boehmite can be produced by carbonizing, alkaline, acidic, neutralizing, and aluminumalcoholate processes. Activated alumina balls are made from FCA by rolling forming method. Activated alumina with different shapes （ strip, trifolium shape, and butterfly shape） are made from pseudo-boehmite by oil-ammonia column forming method, extrudation shaping method, and spary-drying process. At last, several modification methods which may improve physical-chemical properties of activated alumina are summarized.
