  • Publication number: 20230279306
    Abstract: A method for producing briquettes made of a waste material includes provisioning of at least one metal and at least one organic material. The waste material is mechanically prepared in a single or multiple stages and at least one first fraction of the waste material is separated. A briquette mixture containing the at least one first fraction is produced, wherein the at least one first fraction has a calorific value of 0 MJ/kg to 30 MJ/kg. A calorific value of the briquette mixture is adjusted by varying at least the first fraction. The briquette mixture is introduced into a briquetting device and pressed into briquettes. Briquettes with a calorific value of 5 MJ/kg to 30 MJ/kg and with a maximum copper content of 0.1 wt % to 20 wt % are produced.

  • Publication number: 20230193421
    Abstract: A method and an industrial plant for separating a waste material comprises at least one metal and at least one organic material. A separated fraction of the waste material is provisioned which is isolated from the waste material in the course of a mechanical preparation operation. The separated fraction comprises briquettes produced from the waste material, and optionally a coarse fraction of the waste material or of another waste material. A reactor is charged with the separated fraction and gas containing oxygen is introduced into the reactor and the separated fraction is combusted in an incomplete combustion process. The separated fraction is melted into a liquid slag phase and into a liquid metal-containing phase. The slag phase and/or the metal-containing phase are poured off from the reactor.

  • Patent number: 10472689
    Abstract: The present invention relates to a method for pneumatically blowing a powdery substitute reducing agent in a dense flow process, by means of a transport gas, into a gasification reactor, or via a tuyere into a blast furnace. The substitute reducing agent is gasified in a gasification reaction. The transport gas comprises a fuel gas, the constituents of which or the oxidation constituents of which are at least partly involved in the gasification reaction.
