Kinetics of wet flue gas desulfurization by urea is studied here, based on which reaction series and reaction rate constant are defined. 通过对尿素湿法烟气脱硫过程动力学的研究,确定其反应级数及反应速率常数。
Addition of urea to the solution of β-cyclodextrin increased the polarity of β-cyclodextrin cavity and decreased the formation constant of pyrene-β-cyclodextrin inclusion complex, proving that "hydrophobic interaction" was one of the binding forces of cyclodextrin inclusion complex. 结果表明脲素的加入使环糊精内腔极性增大,芘-β-环糊精包络物形成常数减小,这说明疏水相互作用是环糊精包络物形成动力之一。
The effects of urea thermal decomposition rate constant, initial particle diameter and exhaust flow rate on the calculation results are examined to further verify reasonableness of the model. 分析了尿素热解反应速率常数、喷雾初始粒子直径、排气流速对计算结果的影响,进一步验证了文中所选模型的合理性。
