  • Patent number: 4150548
    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.
