  • Patent number: 8308912
    Abstract: A method for pyrogasification of organic wastes that employs a vertical furnace filled with metal masses in the shape of metal toroids (2) previously raised to a high temperature (500 to 1100° C.) and organic materials to be pyrolyzed. It also employs a furnace for heating toroids transported by an Archimedes screw driven by a gear motor, as well as a separator for recovering the mineral residues, whereby separation between the toroids and residues is effected with the aid of a screen and an Archimedes screw driven by a gear motor.
    Type: Grant

  • Publication number: 20090218209
    Abstract: The method is characterised in that the thermal energy necessary for thermolysis of the waste carried out in the absence of air is provided by a heating mass, comprising steel balls (9), running in the furnace (1) co-currently with the waste. The method may be applied to household waste, sewage work residues, hospital wastes, wastes of risk to the agro-food industry and in a general manner to all wastes containing organic matter be it of urban, agricultural or industrial origin.
