摘要：本文采用双搅拌无梯度气液反应器实验研究了Fe(III)-EDTA吸收H2S的反应动力学。建立并求解了H2S吸收数学模型 ,实验确定 Fe(III)-EDTA吸收H2S的化学反应速度常数为: RT-6292011RTk-62920112e1053.4= 实验表明:该吸收反应为双分子二级不可逆反应。实验结果与数学模型值符合较好。
In this paper, an investigation on the kinetics of hydrogen sulfide absorption by ferric chelates of ethylene-diamine-tetraacetic acid (EDTA) was made through the experiment using a double-mixed gradientless gas-liquid contactor . The mathematical model of the macro-kinetics of hydrogen sulfide absorption by ferric chelates of EDTA was established and the rate constant for the reaction was obtained as follows : RTk62920112e1053.4-= According to experiment, it is indicated that the absoption appeared to be a second order reaction. The experiment results of chemical absorption enhancement factor were in good agreement with the mathematical model.
