摘要: 以萘为模型化合物,采用固定床反应器研究了不同温度和表观气速下GH-8活性炭对萘的吸附行为,以Yoon-Nelson模型对实验数据进行拟合,得到模型参数kYN=0.20 h-1, kYNt=51.404-0.166T+0.292/u. 采用传质区模型预测了萘在活性炭床层上的传质区长度及其移动速度,实验值和预测值的最大相对偏差小于10%.

关键词: 活性炭, 吸附, 萘, 固定床, 温度, 表观气速

Abstract: Adsorption performance of naphthalene on activated carbon GH-8 at different temperatures and superficial velocities was studied with a fixed bed reactor. Model parameters were obtained by fitting to Yoon-Nelson model, kYN=0.20 h-1 and kYNt=51.404-0.166T+0.292/u. Mass transfer model was used to predict the length and moving velocity of mass transfer zone. The calculation results showed that the maximum relative deviation between the calculated and experimental values was less than 10%.

Key words: activated carbon, adsorption, naphthalene, fixed bed, temperature, superficial velocity
