Mn (II)/AC adsorbents were prepared by ultrasonic impregnation. The 2 wt. % Mn/AC showed best adsorptive performance, and the optimal adsorption temperature was 313 K. Benzene, methylbenzene, and naphthalene were used to explore the adsorptive selectivity of Mn/AC, indicating that Mn could enhance the adsorptive capacity but could not improve the adsorptive selectivity. The adsorptive mechanism was mostly like to be π-complex. Adsorptive isotherms and kinetics were investigated, and the parameters were calculated. The R2, RMSE, and AICc were used to assess the optimal model. The results showed that Temkin adsorptive isotherm was more suitable to describe the isothermal data; the MPnO kinetics model was more superior to other kinetic models. The order of reaction was between 1 and 2. The outcome of adsorptive thermodynamics indicated that removal of DBT onto Mn/AC was a spontaneous and exothermic process.

活性炭负载锰(II)对模型燃料中有机硫的吸附脱硫:平衡,动力学和热力学
通过超声浸渍制备Mn(II)/ AC吸附剂。2重量%。%Mn / AC表现出最佳的吸附性能,最佳吸附温度为313K。苯,甲基苯和萘用于探讨Mn / AC的吸附选择性,表明Mn可以增强吸附能力但不能改善吸附能力。选择性。吸附机理主要是π-复合物。研究了吸附等温线和动力学,并计算了参数。的- [R 2,RMSE,和AIC Ç被用来评估最佳模型。结果表明,Temkin吸附等温线更适合描述等温数据。MPnO动力学模型优于其他动力学模型。反应顺序为1至2。吸附热力学的结果表明,将DBT去除到Mn / AC上是自发的且放热的过程。
