Destruction of carbonaceous material, and inert solid material formed by reaction of carbonaceous material with sulphur.

摘要

Carbonaceous material, such aspolychlorinated biphenyl, is rendered non-toxic by reaction with sulphur in an inert atmosphere at a temperature of 500 to 1500 DEG C, so as to form an inert solid consisting essentially of carbon and sulphur, and being substantially free of unreacted carbonaceous material. The resulting solid is an inert, refractory material which is non-flammable, substantially insoluble in all known solvents (including aqua regia) and electrically conductive.
