活性氧化铝的生产及其改性

Abstract

Abstract: 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 aluminum-alcoholate 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.

Key words: activated alumina, FCA, pseudo-boehmite, modification
