Abstract
A process for absorbing noxious components such as SO.sub.x, NO.sub.x, and HX from a gas such as a flue gas at temperature below 250.degree. C. is improved by contacting the gas with a conditioned solid acceptor that contains divalent metal oxide, hydroxide or both coated onto exfoliated vermiculite and/or expanded perlite. Before use (to enhance its absorption of noxious components) conditioning can be done by heating the hydrated acceptor at temperature of at least about 400.degree. C. for a short time.
