CA 2187490

An activated carbon body and method of making the body which involves providing an inorganic substrate, a synthetic polymeric carbon precursor, and an adsorption enhancing additive which can be sulfur and/or oil which is non-miscible with and non-reactive with the carbon precursor, contacting the inorganic substrate with the carbon precursor and the adsorption enhancing additive to coat the substrate therewith, curing and carbonizing the carbon precursor, and activating the carbon to produce a coating of activated carbon on the substrate and form the activated carbon body. Another method involves forming a mixture of the carbon precursor, adsorption enhancing additive, which can be sulfur, phosphoric acid, and/or the oil, temporary organic binder, optional forming aid, and fillers, shaping the mixture into a body, followed by curing, carbonizing, and activating to produce a shaped body of activated carbon. In use, a workstream is passed through the activated carbon body for adsorption of one or more components by the activated carbon.
