【摘要】 研究了铬酸钠碳化反应动力学,在1个2 L反应釜内,通过监测反应过程中CO2压力的变化,计算反应速率,避免了因逆反应过快造成的溶液取样分析的困难。实验发现反应速率有一个下降-升高-下降的变化过程。通过反应机理分析,导出了动力学方程,并根据动力学方程较好地解释了实验现象。更多还原

【Abstract】 Carbonation kinetics of aqueous sodium chromate was studied.A 2 L autoclave was used as the reactor.Carbonation reaction rate was calculated by means of measuring the pressure change.A kinetics equation was(proposed) through analyzing the mechanism of the reaction.Based on the equation,the experimental results were(explained) well.更多还原
