Abstract

The invention relates to a device for thermally treating granular solid matter for the purpose of carrying out endothermic reactions. CO2 and/or water is removed from the solid matter in a reactor by burning fuel to generate a combustion gas in the reactor, vortexing the solid matter with the combustion gases in the reactor, using hot exhaust gas from the reactor to pre-heat the solid matter and removing the solid matter from the reactor. The reactor used is an approximately cylindrical, horizontal cyclone with an approximately horizontal axis of symmetry and vortex. Fuel, solid matter and gases are supplied in an inlet zone of the reactor while a rotation vortex is formed in said inlet zone and solid matter and hot gas are removed from an outlet zone of the reactor.
