Breakthrough behavior of diethyl sulphide vapors on carbon systems such as active carbon, NaOH/CrO3/C, NaOH/CrO3/EDA/C and RuCl3/C has been studied by using modified Wheeler equation and the same was used to calculate the pseudo-first-order rate constant (kv) and kinetic saturation of capacity (W(e)) values. Effects of various parameters such as bed height, air flow rate, concentration and temperature on the above parameters have also been studied. Rate constant was found to be increasing with air flow rate, while W(e) was found to be invariable. Both kv and W(e) decreased with the increase in temperature, however, no significant effect on W(e) and kv was observed due to concentration change. The values of kinetic saturation capacity were used to predict the service lives/breakthrough times of carbon beds (when used in filtration systems).
通过使用修正的惠勒方程研究了二乙硫醚蒸气在活性炭、NaOH/CrO3/C、NaOH/CrO3/EDA/C和RuCl3/C等碳体系上的穿透行为,并用该方程计算了伪一级速率常数(kv)和动力学饱和容量(W(e))值。还研究了床层高度、空气流速、浓度和温度等各种参数对上述参数的影响。发现速率常数随空气流速增加而增大,而W(e)不变。kv和W(e)均随温度升高而降低,然而,浓度变化对W(e)和kv没有显著影响。动力学饱和容量值用于预测碳床(用于过滤系统时)的使用寿命/穿透时间。
