摘要：通过静态吸附实验研究了乙酸乙酯在比表面积1 269.254 m^(2)·g^(-1)、孔容0.801 cm3·g^(-1)的树脂基活性炭上的吸附行为,分析发现吸附过程符合Langmuir等温吸附模型,模型拟合相关系数R2为0.994,理论吸附容量qe为420.89 mg·g^(-1)。建立了固定床吸附工艺的数学模型,通过与吸附实验数据对比,计算得到的绝对平均误差AAD值为0.034,分析表明建立的数学模型对于描述活性炭吸附乙酸乙酯的穿透曲线是合理的。用已验证的数学模型,在Aspen Adsorption上对工艺进行了数值模拟,进一步探索了进料流量、操作压力、吸附剂用量和吸附剂堆积密度对吸附过程的影响。模拟结果表明,通过减小进料流量,提升操作压力、增加吸附剂用量及堆积密度,可有效延长穿透时间并提升床层利用率。
The adsorption behavior of ethyl acetate on resin based activated carbon with a specific surface area of 1269.254 m^(2)·g^(-1) and a pore volume of 0.801 cm3·g^(-1) was studied through static adsorption experi-ments.The analysis showed that the adsorption process followed the Langmuir isotherm adsorption model,with a fitting correlation coefficient R2 of 0.994 and a theoretical adsorption capacity qe of 420.89 mg·g^(-1).A mathematical model for fixed bed adsorption process was established.By comparing with adsorption ex-perimental data,the absolute average error AAD value calculated is 0.034.Analysis shows that the estab-lished mathematical model is reasonable for describing the breakthrough curve of activated carbon adsorp-tion of ethyl acetate.A validated mathematical model was used to numerically simulate the process on Asp-en Absorption,further exploring the effects of feed flow rate,operating pressure,adsorbent dosage,and adsorbent packing density on the adsorption process.The simulation results show that by reducing the feed flow rate,increasing the operating pressure,increasing the amount of adsorbent and packing density,the penetration time can be effectively extended and the bed utilization rate can be improved.
