<p>A process for the thermal conversion of organic matter in a continuous batch manner is disclosed. Organic waste material is loaded into individual ones of a plurality of serially arranged foraminous containers having loading doors. The doors are closed and the loaded containers sequentially advanced into the entrance end of a tank of molten metal. The molten metal is maintained at a temperature above 600 degrees F, with a primary array of heating tubes disposed in the lower reaches of said tank. Then, loaded containers are conveyed horizontally along said tank above said heating tube array to permit conversion of the organic waste material within said containers as said heated molten metal flows through the containers in contact with the waste material and rises upwardly from the containers together with hydrocarbon gases and vapors. Retention means are provided within said tank, serving to resist buoyancy of said containers and maintaining the horizontal disposition of same during the majority of transport therethrough. A gas and vapor collection assembly is provided atop said tank including a hood having opposite lower edges disposed beneath the top surface of said molten metal so as to maintain an oxygen-free atmosphere within said collection assembly and allow collection of hydrocarbon gases and vapors rising from said bath top surface. The containers are thereafter withdrawn from said tank outside the confines of said hood lower edge and reusing said containers by the subsequent reloading of organic waste material therein prior to advancement into the entrance end of said tank.</p> |
