Assessing the efficiency of zeolites in BTEX adsorption: Impact of pore structure and humidity in single and multicomponent systems

Among volatile organic compounds (VOCs), benzene, toluene, ethylbenzene and o-xylene (BTEX) have attracted global attention because of their high toxicity to the environment and human health. Adsorption is considered one of the most efficient, simple and low-cost technology for VOC pollution control...

In this study, the adsorption capacity of BTEX of seven zeolites belonging to the structural families LTA, MFI, BETA, MOR and FAU have been investigated. Zeolites have been characterized by X-ray fluorescence and nitrogen sorption measurements. The relationship between the adsorption capacity and physicochemical parameters was investigated.

Si/Al ratio was a key factor in determining adsorption performance under humidity conditions with the best adsorption capacity reaching 16.9 mg/g.
