<p>A process for the thermal treatment of highly chlorinated heavy hydrocarbon residues that comprise hexachlorethane and/or hexachlorobutadiene, together with chlorinated aromatic hydrocarbons and, optionally, tar-like products, comprises bringing a mixture of the said compounds and one or more C2- 4 hydrocarbons and/or C2- 4 chlorinated hydrocarbons capable of reacting with free chlorine in the gaseous state into a single solids-free reaction zone having a ratio, as hereinbefore defined, of the total surface of said reaction zone to the cross-section of said reaction zone higher than 500 under conditions including a temperature ranging from 400 DEG to 550 DEG C., and a turbulent flow rate, i.e. having a Reynolds mean-value number higher than 2000, whereby the production of non-cyclic light chlorinated hydrocarbons containing not more than four carbon atoms in the molecule is maximized.</p> |
