Abstract

A rotary tube reactor, having at least one treatment line composed of tubes whose individual sections have gas chambers which are sealed from each other and wherein each section has a gas outlet and adjacent sections are joined together by material passages, is used for thermal treatment. In accordance with the invention, the reactor is used for the thermal treatment of carbon containing materials, the production of activated carbon, the activation of zeolite granules, the production of pyrophorous metals in the form of powder to lumpy solid materials and substances in liquid form with the evolution of gas.
