Patent ID: 8199790

Claim:
A reactor vessel for plasma gasification reactors wherein feed materials are introduced into said reactor vessel and subjected to high-energy generated by a plasma generating means so that the feed materials are dissociated into metals, slag and organic gases, said reactor vessel comprising: an upper portion and a lower portion, said lower portion for the containment of a first layer of molten metal and a second layer of slag and having a substantially uniform width, said upper portion being for the containment of organic gases and having a volume that permits residence time of a molecule of said organic gases of about 2 seconds a steel shell; multi-layered wall housed within said shell defining a chamber, said multi-layered wall having a first layer comprised of one or more sublayers of high-density refractory material, a second layer comprised of a medium density refractory material, and a third outer layer of low density insulating materials; a refractory lined bottom housed within said shell; a refractory lined top within said shell; first and second openings of said vessel defined in the wall of said vessel on opposing sides thereof in said lower portion directly above the slag layer for the introduction of said feed materials into said reactor chamber, said first and second openings are offset with respect to the center of the vessel; and an exit defined in said top for venting said organic gases.
