        Light hydrocarbons in coke-oven gas, hydrocarbon-synthesis waste gases, etc., owing to their low concentration, are usually recovered by means of active C.  The technique is described and details are given of the working of an active-C plant at a Fischer-Tropsch hydrocarbon-synthesis works.
