Abstract: Waste products, particularly scrap metal, adulterated by organic components, is pyroprocessed by: (1) shredding the adulterated scrap metal into particles having a maximum size of 5 cm.; (2) in a pyrolysis stage operating at a temperature of approximately 550.degree. C. to 600.degree. C. converting the particles into solids and pyrolysis gas; (3) in a mechanical processing stage separating the solids into unadulterated metal and pyrolysis coke; and (4) in a high-temperature gasification stage into which an oxidizing agent and, optionally, metallurgical coke is introduced converting the pyrolysis coke together with pyrolysis gas stemming from the pyrolysis stage into a heating gas free of organic substances.

Abstract: An arrangement for the gasification of fuels with oxygen or oxygen-containing gases and steam, includes a shaft-like vessel for receiving solid charging stock. A gas discharge duct is provided on the upper end of the vessel and a primary gas chamber is in connection with the shaft-like vessel on its lower end via a passage. In the primary gas chamber a burner is provided, which includes feedings for oxygen or oxygen-containing gases as well as for fuels. A trough for receiving slag is arranged below. the primary gas chamber and a supporting bottoms is provided between the trough and the shaft-like vessel, reaching into the primary gas chamber, for the formation of a dumping material bed of the solid charging stock facing the burner by one dumping surface. In order to be able to gasify low-quality fuels into a high-quality product gas, the primary gas chamber includes a charging opening for charging a charging stock to be gasified.

Abstract: When gasifying fuels with oxygen in a shaft-like furnace adapted to receive solid charging stock and including a primary gas chamber on its lower end to be charged by at least one burner, a fixed bed is formed in the primary gas chamber by the charging stock. The charging stock is gasified by the hot offgases from the burner. The gas forming, upon passage through the fixed bed, is extracted from the furnace as a product gas. In order to keep the product gas free of impurities that constitue a load on the environment and limit its usability, such as tar and other higher hydrocarbons, an oxygen-containing gas is injected into the furnace space filled by the product gas and a slight portion of the product gas is burnt.

Abstract: There is disclosed a method for processing heavy-metal-containing residues from the chemical industry. For an economical and at the same time ecologically safe processing of the heavy-metal-containing residues, the heavy-metal-containing residues are introduced into a primary-gas reaction zone of a shaft gasifier containing at least one solid bed of carbon-containing material. Slag-forming substances are introduced together with the charge substances and/or together with the solid-bed formers to absorb and set the heavy metals. The lower zone of the solid bed is maintained at a temperature above the slag and ash melting temperatures. The viscosity of the slag is less than 100 poise.
