采用离子交换树脂法吸附铬(Ⅲ),通过树脂选型确定强酸性阳离子交换树脂001×14.5对铬(Ⅲ)吸附容量最大,用所选的001×14.5树脂研究铬(Ⅲ)的吸附性能。静态吸附实验表明:转速大于120 r/min时,对树脂吸附的影响可忽略,即外扩散基本消除,pH=7.0时,吸附最佳,铬(Ⅲ)吸附率随树脂用量的增加而增大;001×14.5树脂吸附铬(Ⅲ)的过程符合Langmuir等温曲线,且为优惠吸附;吸附过程符合拟二级动力学方程,吸附过程的表观活化能Ea=23.4 kJ/mol,颗粒内扩散为吸附速率的主要控制步骤;用1 mol/L的硫酸对吸附后的饱和树脂进行脱附再生,脱附率可达99%。 相似文献

In this paper, a reactive distillation (RD) column was applied for synthesis n-butyl acetate from n-butanol and acetic acid. The Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic model and an equilibrium stage model for separation were employed to study the RD process. The results obtained from the equilibrium stage model agreed well with the experiments. The effects of operating variables on the n-butanol conversion and n-butyl acetate purity were further investigated. The optimal column configuration for the production of n-butyl acetate was designed with 5 rectifying stages, 8 reaction stages and 13 stripping stages by the simulation study. According to the simulation results, n-butanol conversion and n-butyl acetate purity all reached greater than 96%. 相似文献
