摘要:
采用分形理论对复合吸附剂的孔隙结构进行了描述。结合Darcy渗流理论和吸附动力学理论,对复合吸附剂的传质性能进行了分析,建立了气体渗透率的理论模型,讨论了吸附过程对复合吸附剂气体渗透率的影响。结果表明,复合吸附剂的气体渗透率主要取决于孔隙结构中的最大孔径。在吸附过程中,复合吸附剂的气体渗透率显著下降。和吸附前相比,复合吸附剂在吸附后的气体渗透率降低了约45%。
Abstract:
The porous structure model of composite adsorbent was constructed with fractal theory. Mass transfer performance of composite adsorbent was investigated with Darcy percolation theory, coupled with adsorption dynamics. The theoretical model of gas permeability was established in this paper. The influences of adsorption process on gas permeability of composite adsorbent were discussed. It was concluded that gas permeability was sharply decreased with smaller maximum pore size Dmax. It was also concluded that mass transfer performance was significantly influenced by adsorption process. The gas permeability was reduced by around 45% due to the volume variation of adsorbent material in adsorption process.
