Method for controlling chemical reaction in a molten metal bath

In a method for chemical reaction of a waste, wherein the waste is directed into a reactor within which a molten metal bath is disposed, the molten metal bath causing chemical reaction of at least a portion of the waste, whereby an intermediate component and atomic constituents are formed, a portion of the intermediate component combining with an off-gas formed in the reactor and being emitted from the reactor with the off-gas:

• The improvement comprising separating at least a portion of the intermediate component from the off-gas to form an intermediate stream and directing said intermediate stream into the reactor for chemical reaction of the intermediate component returned to the reactor in the intermediate stream to atomic constituents and subsequent exothermic reaction of at least a portion of the atomic constituents with a component of the molten metal bath, whereby heat generated by the exothermic reaction initiates additional chemical reaction of the waste and of the intermediate component, thereby controlling chemical reaction of the waste.

• The improvement comprising separating at least a portion of the intermediate component from the off-gas to a second reactor having a second molten metal bath disposed therein for chemical reaction of the intermediate component in the second reactor to form atomic constituents and for subsequent reaction of at least a portion of the atomic constituents with a component of the second molten metal bath, thereby controlling chemical reaction of the waste.
