以旋转填料床为脱附设备，采用准二级动力学模型研究了间苯二酚在活性炭上的脱附行为及动力学，并与传统固定床进行了对比. 结果表明，在温度20℃、液体流量50 L/h、超重力因子32.63及pH值11、脱附剂乙醇40wt%、脱附时间90 min的优化条件下，间苯二酚脱除率达93.90%，比传统固定床提高了58.54%，超重力强化了液固传质，对脱附有利；脱附速率常数随液体流量和超重力因子增大而增大，由以超纯水为脱附剂时的13.27×10?3 g/(mg?min)提高到以乙醇为脱附剂时的25.48×10?3 g/(mg?min).

The desorption behavior and kinetics of resorcinol from activated carbon in rotating packed bed were studied by the pseudo-second-order kinetic model, compared with that in the traditional fixed bed. The optimal operation conditions were determined with temperature of 20℃, high gravity factor of 32.63, pH value of 11, flow rate of 50 L/h, desorption agent ethanol of 40wt% and desorption time of 90 min. In these case, desorption rate of resorcinol reached 93.90%. Compared with the fixed bed, desorption rate increased about 58.54% under the same operating conditions in rotating packed bed. The high gravity technology was beneficial to desorption performance by enhancing the mass transfer from liquid phase to solid phase. The desorption rate constant increased with the increased of flow rate and high gravity factor. In addition, the desorption rate constant improved from 13.27×10?3 g/(mg?min) with ultrapure water as desorption agent to 25.48×10?3 g/(mg?min) with ethanol as desorption agent.
