Abstract : Activated carbon cloth (ACC) was tested to evaluate its ability to maintain physical adsorption properties over an extended series of adsorption/desorption cycles. Adsorption consisted of saturation with a volatile organic compound (VOC). Benzene and acetone were selected as the test VOCs due to their commonality in indoor air and potential threat to human health. Desorption of these VOCs was achieved through direct electrical resistance heating (DERH) regeneration using an alternating current to increase bulk ACC temperature to 140 deg C. The heat generated was due to the resistive property of the ACC'a fibers (resistivity of 1-2 x 1O(exp -2) ohms x cm). jg p.2
