ABSTRACT:
The invention relates to a process for the destruction of waste, like biologically difficult to degrade halogen-, nitrogen-, sulphur-, and/or oxygen containing compounds by thermal hydrogenolysis. The waste materials are heated together with an excess hydrogen and/or hydrogen donor during 1 to 10 sec. to a temperature between 700.degree.-1220.degree. C., followed by quenching the gaseous effluent of the reaction and separating it in a hydrocarbon and hydrogen containing phase and a hydrogen halogenide(s) nitrogen-, sulphur-, and/or oxygen containing compounds containing phase.
Preferably the hydrogenolysis is performed in two steps, first during 1-10 sec. at 700.degree.-900.degree. C. and second during 1-10 sec. at 850.degree.-1200.degree. C.
