Abstract

Abstract: In order to elucidate the patterns of vacuum desorption of volatile organic compounds(VOCs) from activated carbons, the vacuum desorption curves of the VOCs as a function of the temperature were investigated in a fixed bed by choosing 11 types of VOCs (including alkanes, aromatics, alcohols and ketones, and so on) of different chemical structures and molecular sizes. The results showed that vacuum desorption was a highly potential technology for recovering VOCs. Compared with conventional thermal desorption methods, vacuum desorption significantly reduced VOCs desorption temperatures, and allowed high desorption efficiency of greater than 99% and more reuse of activated carbons. The polar surfaces of activated carbon significantly weakened the desorption of alcohols while the non-polar surface was conducive. The surface property of activated carbons barely affected the desorption of the non-polar VOCs. Further, adsorbed alcohols molecules such as methanol and ethanol were arranged perpendicular to the surface of activated carbon in a way that hydroxyls of alcohols directly contacted with the carbon surface. This arrangement led to carboxyl groups of activated carbons prone to be removed or be changed into lactone in the vacuum thermal desorption process.
