对低浓度三氯乙烯在活性炭固定床中的吸附净化作了系统研究。测定了三氯乙烯-空气-活性炭系统吸附等温线及在40×120mm活性炭固定床中穿透曲线;建立了三氯乙烯活性炭固定床吸附数学模型并用此预测了穿透曲线,实验与计算结果对比表明模型预测与实验结果吻合良好。
A systematic study on the adsorption and purification of trichlorethylene with low concentration in a fixed bed of activated carbon was carried out. The adsorption isotherms of trichlorethylene-air-activated carbon system and the breakthrough curves in fixed bed of 40 × 120mm activated carbon were established. The mathematical model of fixed bed adsorption of trichlorethylene activated carbon was set up and the breakthrough curves were predicted. The results of experiments and calculations The comparison shows that the model prediction is in good agreement with the experimental results.
