The modified Wheeler-Jonas model is well known for its good prediction of breakthrough times for organic vapors on activated carbon beds. To use this model adequately one must estimate the overall adsorption rate coefficient kv. In this work a new equation is proposed to calculate kv. The relevant parameters of this equation are the airstream velocity, the affinity constant beta of the organic vapor, and the mean diameter of the carbon particles. Very accurate predictions were obtained for breakthrough times on a wide range of carbons using the calculated values of kv. Compared with other models, this model shows a higher accuracy and a lower degree of uncertainty.
改进的惠勒-乔纳斯模型以其对活性炭床上有机蒸汽穿透时间的良好预测而闻名。要充分使用该模型，必须估算总吸附速率系数kv。在这项工作中，提出了一个计算kv的新方程。该方程的相关参数是气流速度、有机蒸汽的亲和常数β和碳颗粒的平均直径。使用计算得到的kv值，在广泛的碳材料上对穿透时间进行了非常准确的预测。与其他模型相比，该模型具有更高的准确性和更低的不确定性。
