Adsorption–desorption characteristics of methyl ethyl ketone with modified activated carbon and inhibition of 2,3-butanediol production

Abstract: Activated carbon (AC) is seldom applied for recovering ketone-based volatile organic compounds because of safety concerns. Adsorption of methyl ethyl ketone (MEK) with AC is a highly exothermic reaction that potentially causes fires in AC beds. Moreover, 2,3-butanediol (BDO) is produced in the desorbed solvent, causing yellowing and odor of the recovered solvent. This study applied a continuous adsorption-desorption apparatus for evaluating the operating capacities and BDO concentration in recovered MEK contai… Show more

“…This phenomenon allowed us to discuss the adsorption/desorption mechanism on the molecular level. This flexible material does not suffer from undesired side reactions that can occur during the adsorption/desorption processes of volatile carbonyl compounds onto/from activated carbon materials . From this perspective, this work proposes an alternative direction for the development of efficient carbonyl adsorbents.…”

“…This flexible material does not suffer from undesired side reactions that can occur during the adsorption/desorption processes of volatile carbonyl compounds onto/from activated carbon materials. 24 From this perspective, this work proposes an alternative direction for the development of efficient carbonyl adsorbents. The substrateselective nature of the adsorption is expected to lead to future comprehensive explorations of this material for use in industrial applications, not only as an adsorbent for polar VOCs, but also as a separation material for processes such as the adsorptive desulfurization of fuels.…”
