Apparatus and process for the treatment of a material under pyrolytical conditions, and use thereof

摘要

A treatment apparatus (1) for treatment of a material, e.g. iron ore, under pyrolytical conditions, comprises a housing (2) having an extrusion screw (3) for processing the material. An independent claim is also included for treatment of a material under pyrolytical conditions in three phases, comprising a heating phase of the material, a reaction phase in which the material may become at least partially plastic and a third phase in which one or more processed products are formed. The processed products are formed from the material in a housing while the material and the products in the housing are transported forcibly.
