Abstract:
Process for treating humid residues containing oxidizable organic matter and having a dry matter content of at least 10% by weight, based on the total weight of the humid residues, comprising the steps of:a) introducing said residues into a rotary furnace having a refractory lining and containing a thermo-transfer agent comprising solid and granulous inorganic particles; b) heating said residues in admixture with said thermo-transfer agent in the presence of chemically active species and UV radiation generated electrically, while rotating the furnace, so as to dry said residues without melting said residues and said thermo-transfer agent and cause oxidation of the organic matter and formation of gases, the oxidation being catalysed by the chemically active species and the UV radiation; and c) expelling the gases from the furnace.
