Mechanism of Separation of Contaminants from Activated Carbon by Closed Cycle Temperature Swing Desorption

In this paper, the mechanism of separation volatile organic compounds (VOCs) from activated carbon adsorption beds during closed cycle temperature swing desorption was studied. Toluene gas at different concentrations used as for to regenerate saturated with toluene. This research advances our understanding contaminants and process by which waste a background concentration desorbs in hot concentration, establishing technological foundation carbon. When 2 g/m3, average rates unit 10 cm 40 min 60 were largest, 0.0099 0.0067 g/ (g•min), respectively. The fit Bangham rate equation best. toluene g/m3 filling length layer cm, constant highest, 0.0152 min−1.
