Studied the adsorption capacity of SO2 of the active carbon of the brand AP-B by absorption of sorbtiva from dry gas, which contains oxygen, done using a laboratory setting and in partial pressure of sulfur dioxide of less than 1kPa, and temperature 293-313 K. Submitted the calculated equation, which adequately describes the dependence of the adsorption capacity of coal from the adsorption conditions. It is established that the volume sorbed SO2 is oxidized on carbon to SO3 in an oxygen concentration in the gas phase of 5%. Showed the possibility of applying of adsorption-catalytic process, using active carbons for purification of waste gases of plants of sulfuric acid. Operating coal recovered by washing with water with the introduction of the resulting dilute sulfuric acid to the irrigation cycle of monohydrate absorber.
