A rotating packed bed, which replaces gravity with centrifugal force, was adopted in this study. Under a centrifugal field, the operating range can be covered in higher gas and liquid flow rates due to the reduced tendency to flood, and mass transfer was also enhanced. The experimental results showed that the mass transfer coefficient was increased with increasing rotor speed, to the power ranging from 0.28 to 0.51. Comparing with the model-predicted values and the experimental data of conventional packed beds, KG a obtained from our experiment was approximately an order of magnitude higher.application/pdf50740 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所吸收有機揮發物轉填充床高重力場質傳係數AbsorptionVOCRotating Packed BedHigeeMass Transfer Coefficientreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9248/1/892214E002034.pdf
