Résumé

A rotary adsorber with the metal ion-exchanged zeolites shows that it has the high efficiency of nitrogen monoxide (NO) abatement. The equilibrium sorption isotherms of NO on the copper ion-exchanged zeolite were experimentally determined, and with these experimental data, the differential heat of sorption and the integral heat of sorption were calculated. The mechanism of coupled heat and mass transfer in rotary adsorber with metal ion-exchanged zeolites has been investigated. A numerical scheme RAZ has been developed for simulating the performance of rotary adsorber. The results of the finite difference calculations show that the shape of the isotherm has a great effect on adsorption performance. The heat and mass transfer properties is characterized by the number of transfer units NTU, the larger the NTU, the better adsorption performance. However, when NTU is up to 8, the performance will not improve significantly. Large adsorption heat effects has a detrimental impact on adsorption. High fractional removal over 95% was obtained at optimum condition.
