Abstract
The gas stream obtained from the pyrolysis of solid organic wastes and containing halogens, particularly chlorine in the form of the corresponding hydrogen halide is processed to obtain a halide free pyrolytic oil. The gas stream after solids removal is contacted with a solid metal halide acceptor above the dew point of pyrolyzate to form the corresponding metal halide which may be discarded. As an alternative the metal halide can be treated to release the hydrogen halide which is recovered as an acid and the acceptor regenerated for recycle. The preferred acceptor is calcium carbonate.
