摘要
Abstract
Pseudo-boehmite was prepared by NaAlO2-CO2 method.The effects of sodium metaaluminate concentration,reaction temperature,pH value,aging temperature,aging time,washing times,washing water temperature and drying temperature on the solubility of pseudo-boehmite were investigated.The experimental results showed that the concentration of alumina in sodium aluminate solution is between 30～40 g/L;De-composition temperature 30～40℃;The pH value of the decomposition endpoint is 10.5～10.7;Aging temperature:90～95℃;Aging time:3 hours;Wash4 times;Washing water temperature 60℃;At a drying temperature of 80～90℃,the prepared pseudo boehmite exhibits the best gel solubility,with a gel solubility index of up to 95％.关键词
