【 摘 要 】

In order to study the mechanism of fine particle removal from flue gas by emulsion liquid membrane (ELM), adsorption model was investigated. Three adsorption kinetics equations (first order, second order and third order) were applied to simulate the uptake of fine particle from flue gas by ELM. The results show that the experimental data was fitted better with the pseudo-second-order equation model than those with other equation models. In order to further study the diffusion mechanism, the intraparticle diffusion model and the liquid film diffusion model were employed to study the adsorption mechanisms of ELM. The result suggests that the two stage adsorptions happened for fine particle from flue gas by ELM and these steps accord with intraparticle diffusion models.
