NOVELTY - Electrical reactor (I), for reforming a gas comprising hydrocarbon and/or organic compound (both optionally substituted) having carbon, hydrogen or heteroatom in the presence of an oxidizing gas, comprises: an enclosure (A); a reaction chamber (B); a supply of a gas to be reformed; supply of oxidizing gas; an outlet; optionally an electric source; and optionally heat input to the lining resulting due to the generation of electron flow.    USE - (I) is useful for: the production of synthesis gas (methanol) and preferably for implantations having an electrical consumption of 1-5 MW; valorization of energy and/or chemical products of biogas generated in places of medical dumping; and the production of hydrogen for: fuel applications linked with road transport (e.g. as a supply for automobiles and buses) and portable or stationary applications (e.g. for the supply of fuel batteries used in residence and vehicles). The process is useful for desulfuration of gas (sulfur) (all claimed).    ADVANTAGE - (I): reduces the cost of reforming gas; inexpensive and easily available in the market; eliminates problems associated with the usage of conventional catalysts; is modular, compact, flexible and provides high yield.    DETAILED DESCRIPTION - Electrical reactor (I), for reforming a gas comprising hydrocarbon and/or organic compound (both optionally substituted) having carbon, hydrogen or heteroatom in the presence of an oxidizing gas, comprises: an enclosure (A); a reaction chamber (B) (provided with at least two electrodes and situated within (A)), comprising a conducting lining material (C), which is a reforming catalyst (where the lining is isolated electrically from the metal wall of (A) to avoid short-circuit); a supply of a gas to be reformed (D); supply of oxidizing gas (optionally distinct from (D)); outlet for gases; optionally an electric source to make the electrodes active and resulting in the generation of an electron flow in the conducting lining between the electrodes (where the lining defines a catalyst (iron or its alloy)); and optionally heat input to the lining (preferably resulting due to the generation of electron flow in the lining). INDEPENDENT CLAIMS are also included for:    (1) electrical process for gas reforming comprising reaction of (D) in the presence of oxidizing gas in (I); and    (2) electrical process for hydrocarbon and/or organic compound reforming in the presence of an oxidizing gas (preferably in the presence of water vapor and/or carbonic gas and/or other gases) in (B) (comprising conducting lining with a metal base defining a porous medium (having the surface volume of more than 400 m2 of exposed surface per m3 of (B) ) serving as heating medium and catalyst medium; two metallic electrodes constituted a pipe and a perforated hollow disc in contact with the lining to carry out the supply of electrical current required for the heating of lining and to facilitate catalysis by movements of electrons) comprising mixing hydrocarbons and/or organic compounds and oxidizing gas; introducing the mixture into the reaction chamber by injection into one of the electrodes; contacting the mixture with the lining; applying of an electron flow to make the electrodes of the reaction chamber active; heating the lining by electron flow and production of a movement of electrons which facilitates catalysis by supply of an electrical current by the two electrodes (where the current is passes directly into the lining); and evacuating and recuperating gas in the reactor by passage into the other electrode.
