-
摘要: 研究了脱硫剂对低浓度SO2吸附过程的传质机理。发现当采用多孔性吸附剂时,共传质过程为内扩散控制。导出简化数学模式并用于计算SO2在吸附过程中的有效扩散系数为10-4~10-5cm2/s。Abstract: Mechanism of mass transfer in low concentration SO2 adsportion process on desulfurizing substance was studied. It was found that the process of mass transfer with porous adsorbent was controlled by inner diffusion. A simplified model was introduced and used to calculate effective diffusivity of 10-4~10-5cm2/s in the process of SO2 adsorption.
