Abstract

Waste or refuse is fed to a first reaction chamber communicating with a second one through openings in the lower portion of a partition between the chambers and hot metal or the like is fed into at least one of the two chambers; gas is extracted from the second chamber and the pressure conditions are such that different liquid levels obtain in the two chambers causing reaction gas to bubble through the openings and the liquid in the second chamber. The principle product gases extracted are hydrogen, carbonoxide and inert gases. Lime is preferably added to the waste to be processed.
