Abstract

According to the intermittent production process of rail transit,combined with the treatment method of adsorption concentration and catalytic combustion,painting exhaust gas depuration equipment with new particle zeolites as the adsorbent was designed.Typical volatile organic compounds,toluene and xylene were used as model molecule for static/dynamic adsorption evaluation.The results showed that the specific surface area and static saturated adsorption capacity of xylene of the multi-porous ZSM-5 were significantly higher than the conventional microporous ZSM-5 and the other two commercial zeolites;The dynamic saturated adsorption capacity of toluene and xylene of hollow-column multi-porous ZSM-5 was 8.62%and 4.48%,which had broad-spectrum VOC adsorption and good hydrophobicity;The multi-porous ZSM-5 maintained good safety,structural stability and stable regeneration performance under the desorption of hot air at 120~200℃.
