Equilibrium adsorption isotherms and rates of thermal decomposition were measured for sodium dodecylbenzene sulfonate (DBS) adsorbed on powdered activation carbon. The rate data were obtained in a thermal gravimetric apparatus operated both at constant temperature (522 to 666 K) and with a constant rate of temperature increase from 298 to 1023 K.

After exhaustion, activated carbon must be regenerated or replaced by fresh carbon. In this study thermal regeneration of saturated carbon with pnitrophenol has been analysed. Three thermal regeneration methods have been tested: (1) pyrolysis, (2) pyrolyisgasifiion and (3) direct gasifiion, the gasifying agents being air and CO2.

 · In our study, carbon was regenerated periodically via Fenton's reaction and returned to service in order to establish process feasibility under field conditions. In the field, up to 95% of the sorbed TCE was removed from GAC during regeneration periods of 5060 hours. Recovery of PCE was significantly slower.

Abstract Thermal swing adsorption (TSA) is widely used as a process in industry for gas purifiion and air treatment. This study enlightens the effects of thermal regeneration of an activated carbon spent with volatile organic compounds (VOCs) on its adsorption capacities. Ketone group VOCs (acetone and methyl ethyl ketone (MEK)) were selected for this study as they are sensitive to ...

Activated carbons are used in hundreds of different purifiion appliions. In many cases, when the carbon is spent or the treatment objective is no longer being achieved, the spent carbons can be recycled via thermal reactivation, a process we refer to as RegenSys®. The main benefits of carbon regeneration/ reactivation are as follows:
