ABSTRACT:
Method and apparatus for purifying an air or gas flow of combustible vaporous or gaseous impurities by passing air or gas through an adsorption filter, desorbing the filter by passing a heated inert gas, and prior to passing the hot inert gas through the adsorption filter, passing a cold protective gas through the adsorption zone thereby preventing undesired ignition of the desorbate and the burning of carbon. Provision is made for spaced closing elements at the gas inlet and the gas outlet of the adsorption chamber with introduction of protective gas in the interspace between the closing elements.
