Abstract: A method of processing a mineral solid mixture, in particular road construction material, containing impurities with aromatic and/or aliphatic hydrocarbons, wherein the solid mixture is heated to a temperature below 570° C., wherein the solid mixture is heated in at least one heated rotating drum-like apparatus and is passed through at least one container and that the solid mixture is heated during or after the heating process, drum-like apparatus and is passed through at least one container, and in that the solid mixture is subjected to a negative pressure during heating or after heating, and in that the hydrocarbons are extracted from the heated solid mixture by the negative pressure and are rendered harmless by thermal combustion.

Abstract: In a process for the continuous conditioning of gypsum plaster, the gypsum plaster is passed from a calcination facility connected upstream to a gypsum plaster cooler in the form of particles. In the gypsum plaster cooler, soluble calcium sulphate anhydrite is initially converted to calcium sulphate hemi-hydrate and calcium sulphate dihydrate to calcium sulphate hemi-hydrate, and crystal defects are eliminated. Subsequently, the gypsum plaster is brought into contact with ambient air and dehumidified by the latter and thereby simultaneously cooled indirectly.

Abstract: A composite membrane comprising organic functional polymers and ceramic nanoparticles (1-100 nm), with the exception of sheet silicates and three-dimensional silicates, with intercalated water and/or a high surface concentration of acidic/basic groups (e.g. hydroxyl) and water. The use of such particles makes possible not only a satisfactorily high mechanical stability of the composite material but also stabilization of the proton concentration necessary for the conductivity in the membrane up to operating temperatures of 300° C. Important factors are the interfaces between polymer and ceramic powder which are formed in the microheterogeneous mixture and allow, if they are present in sufficient number (high proportion of the phase made up of nanosize particles), proton transport at low pressure and temperatures above 100° C.
