  • Patent number: 11999618
    Abstract: The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.

  • Publication number: 20060124445
    Abstract: The invention concerns an electrical reactor for reforming, in the presence of an oxidant gas, a gas comprising at least one hydrocarbon, and/or at least one organic compound, including carbon and hydrogen atoms as well as at least one heteroatom. Said reactor comprises: an enclosure, a reaction chamber provided with at least two electrodes comprising at least one conductive lining material electrically isolated from the metal wall of the enclosure, at least one supply of gas to be reformed, at least one oxidant gas supply, at least one outlet for the gases from the reforming and one electrical source for powering the electrodes and resulting in generation of an electronic flux in the conductive lining between the electrodes and in heating said lining.

  • Patent number: 6376739
    Abstract: A process for treating humid residues containing oxidizable organic mater. The process preferably comprises steps of: a) introducing the residues in a rotary furnace having a refractory lining and containing a thermo-transfer agent; b) heating the residues in admixture with the thermo-transfer agent at a temperature of at least 300° C. in the presence of chemically active species and UV radiation generated electrically, while rotating the furnace, so as to dry the residues and cause oxidation of the organic matter and formation of gases, the oxidation being catalyzed by the chemically active species and the UV radiation; and c) expelling the gases from the furnace. Such a process permits a low cost destruction of polluting material and/or oxidizable toxic material contained in the residues treated.
