| 摘 要： | 在半工业吸附装置上实验研究了边流效应对固定床吸附器穿透曲线的影响，建立了非定态二维数学模型描述这种影响．实验结果表明，在床径／粒径比为90时，固定床内边流效应对穿透曲线影响仍很大，中心与壁面穿透时间相差可达4h，模型预测结果表明，实验结果与预测结果能很好吻合．

| Abstract: | The paper deals with the experimental study on the effect of maldistribution on the break through in a technical column of activated carbon.The effect of maldistribution are described with a 2D model．The result shows that the effect of maldistrbution can not be neglected even when Db/dp=90．The difference of breakthrough between the wall-near zone and the center of the fixed bed can be 4 hours.The calculated results are in good agreement with the experimental ones. |
