Abstract: Gaseous products produced by pyrolytic conversion of materials are treated in a series of stages in a closed system by progressively subjecting the gaseous products to decreasing temperatures ranging from near ambient to cryogenic. Removal and storage of pollutants from the gaseous products is accomplished by condensation resulting from cooling, physical separation by subjecting the gaseous products to centrifugal forces, sub-cooling of the gaseous products, and chemical adsorption by molecular sieves, these operations being carried out in the various stages.

Abstract: Organic and pseudo-organic materials such as waste materials, for example, are processed in a converter system and decomposed into various usable and reusable forms. Inorganic metals and salts are treated likewise in the same converter system and processed into various usable and reusable forms. While being carried by a conveyor through a controlled atmosphere treatment chamber, virtually free from combustion supporting air or other oxidizing agents, the feed material is caused to progressively thermally break down into its more basic constituents which flow out of the material treatment chamber in a continuous liquid and gaseous vapor stream. Negative pressure is applied upstream from the material treatment chamber to lead the liquid and gaseous vapor stream through successive processing stages of collection containers, condensers and gas scrubbers. The variable negative pressure is sufficient to maintain the pressure in the material treatment chamber within a range of slightly above ambient pressure.
