正交试验法优化柠檬酸法氧化铝生产工艺
Orthogonal Optimized Synthesis of Dawsonite from Aluminum Citrate
摘要
Abstract
The conversion of aluminum citrate ( AlCit) to dawsonite is the key step to the alumina process named " AlCit-dawsonite-alumina". The reaction conditions including the dosage of sodium bicarbonate, pH, reaction temperature and reaction time, were found to be related to the conversion of AlCit. Orthogonal experimental design was employed to optimize the reaction condifions. About 76% of AlCit was conversed to dawsonite under the optimized conditions: NaHCO3/Al molar ratio of 5 , pH of 11, temperature of 80 ℃ and reaction time of 3 h, comparing to 65% obtained under preliminary experimental conditions.关键词
