The desorption efficiency and desorption rates of hexane and toluene were studied for low-crosslinked and hyper-crosslinked styrene-divinylbenzene polymers and compared with commercial activated carbon (AC). Hyper-crosslinked polymers, with both micropores (attributed to chloromethylation) and meso/macropores, showed high capacities for high and low VOC concentrations. Low-crosslinked polymers, lacking micropores, only adsorbed high concentration VOC efficiently. Polymers perform effectively for removing gas phase VOC. Their faster desorption kinetics and efficiency support the use of lower energy input regeneration strategies, leading to energy and cost savings. This is an abstract of a paper presented at the A&WMA's 109th Annual Conference & Exhibition (New Orleans, LA, 6/20-23/2016).
