A method for strengthening the chemisorptionsfaehigkeit of carbon with respect to gases

摘要

The present invention is related to a procedure for increasing the chemisorption capacity of carbon impregnated with metallic compounds. By a large number of tests it is amply demonstrated that such capacity may be significantly increased with regard to poisonous gases and gaseous industrial effluents simply by irradiating the impregnated carbon by gamma radiation to a dosage of at least 1 Mrad before the actual sorption process. The said chemisorption capacity may be further increased by performing the irradiation in a nitrogen atmosphere, preferably at a higher partial pressure of nitrogen than in air at atmospheric pressure.
