摘要

　通过对反应进程中体系pH值跟踪

研究铝酸钠浓度、填料转速等因素对pH值变化的影响.结合反应动力学理论分析了碳化机理.研究了旋转填料床反应器中NaAlO2溶液和CO2碳化反应的碳化机理.旋转填料床反应器加速了反应进程

缩短了碳化时间.碳化中期是大量沉淀析出期

该阶段是制备过程中控制Al(OH)3粒度关键阶段.

Abstract

The reaction process is traced by monitoring the pH value

the variation of pH during carbonation versus of concentration and packing rotating speed is studied and Carbonation mechanism is analyzed combining pH value vaziation and reaction dynamics. Based on reaction of sodium aluminate solution and carbon dioxide gas in rotating packed bed reactor Carbonation Mechanism is investigated. Rotating packed bed reactor quicken the reaction proceedure and shorten the carbonation reaction time. Mass is precipitated during the midreaction time

which is the best time for controlling Al(OH)\-3 particle size.
