Abstract

Apparatus for purifying an air or gas flow of combustible vaporous or gaseous impurities by passing the air or gas through an adsorption filter and charging the filter to a predetermined level. After the filter is so charged, the air or gas flow is interrupted and the filter is desorbed by passing a heated inert gas generated by stoichiometric burning of hydrocarbons through the filter.
