This work aimed to explore the property effects of added magnetizable particles on the magnetic intensification of mass transfer between the fluidizing gas and Geldart-B nonmagnetizable particles. A compromise volume fraction (x_vM) of magnetizable particles in the resulting binary admixture was 0.40 to transmit the stabilizing effect of magnetic field to the nonmagnetizable particles and save the bed volume. When x_vM was maintained the same (=0.40), the added magnetizable particles had an optimal size/density to maximize the magnetic intensification. When the gas velocity was three times the minimum fluidization velocity of the nonmagnetizable particles, the optimum size and density ratios between the added magnetizable particles and the nonmagnetizable particles were 0.41 and 2.99, respectively. When the mass fraction was kept constant (=0.77), the lighter magnetizable particles were preferred to transmit the magnetic stabilization. The property effects of added magnetizable particles on the magnetic intensification of mass transfer depended on its effects on the hydrodynamics in the resulting admixture MFB. Provided the added magnetizable particles could make the obtained admixture MFB locate in the magnetic stabilization flow regime, the mass transfer could be significantly intensified. The more stable the obtained magnetic stabilization, the better the magnetic intensification of the mass transfer.

这项工作旨在探索添加可磁化颗粒对流化气体和 Geldart-B 不可磁化颗粒之间传质磁增强的性质影响。所得二元混合物中可磁化颗粒的折衷体积分数 ( x _vM ) 为 0.40，以将磁场的稳定作用传递给_不可磁化颗粒并节省床体积。当x _vM保持不变 (=0.40)，添加的可磁化颗粒具有最佳尺寸/密度以最大化磁增强。当气体速度为不可磁化颗粒最小流化速度的三倍时，添加的可磁化颗粒与不可磁化颗粒的最佳尺寸和密度比分别为0.41和2.99。当质量分数保持恒定（= 0.77）时，较轻的可磁化颗粒更适合传递磁稳定性。添加的可磁化颗粒对传质磁增强的性质影响取决于其对所得混合物 MFB 中流体动力学的影响。如果加入的可磁化颗粒可以使得到的外加剂 MFB 处于磁稳定流态，传质可能会显着加强。获得的磁稳定越稳定，传质的磁增强越好。
