Definitions

• the invention relates to a method and device for carbon dioxide capturing and its transformation into gaseous fuel, finding application in heat engineering and more particularly in heat and thermal power plants and industrial plants with combustion installations.
• EA009601/B1 a plasma gasifier for solid fuel is described, wood mainly, without introducing C0 2 from flue gases for conversion into solid fuel.
• RU2345276C1 describes a technology which aims at obtaining hydrogen after burning liquid or gaseous fuel, with following oxidation of the combustion products, wherein the hydrogen is separated for its use as regenerator of metals from oxides. There is no conversion of waste C0 2 .
• BG51440 a method is described for purifying air, flue gas or similar gas mixtures, which consists of feeding the flue gas or gas mixture to a reactor.
• the device known from BG51440 consists of reactor with chamber; in the reactor at least one electrode is mounted, connected with high voltage system. In the lower part of the reactor an inlet pipe is located; opposite to it on the other side of the reactor is the outlet pipe.
• the object of the invention is to create a method and device for carbon dioxide capturing and its transformation into fuel, wherein the carbon dioxide is not fully recovered, i.e. to elemental carbon, but partly to CO, which is a combustible gas, without the necessity of complicated technology thereof.
• the method and the device guarantee dealing with the environmental issues resulting from the increase of carbon dioxide in the atmosphere.
• the problem is solved with a method for carbon dioxide capturing and its transformation into gaseous fuel, wherein flue gas or gas mixture is fed to a reactor.
• the carbon dioxide alone or in admixture with water vapor and/or methane is subjected to pulsed and/or acoustic treatment and is then passed through the reactor via thermally activated zones with temperature 800 to 1000 °C to produce carbon monoxide and/or synthetic gas.
• the thermally activated zone contains thermally activated lump or granular solid carbon-containing fuel.
• a device for implementing the method comprising a reactor with chamber; at least one electrode is mounted in the reactor, connected to high- voltage system.
• an inlet pipe is located; opposite to it on the other side of the reactor is the outlet pipe.
• the reactor chamber is filled with carbon solid carrier, thermally activated to temperature from 800 °C to 1000 °C.
• the electrodes are needle cathode and flat anode and in the opening of the inlet pipe a rotating plate is fitted for generating pulse effects.
• the reactor chamber is filled with plasma.
• Fig. 1 a - illustrates the preparation of mono gas (CO);
• Fig. 1b the preparation of synthesis gas (CO + H 2 );
• Fig. 1c the preparation of high calorific synthesis gas
• Figure 2 is a schematic view of the device for implementing the method.
• the calorific value of the gases obtained depends on that whether carbon dioxide is mixed with other gases and with which. In some technologies carbon dioxide is separated from other gases: nitrogen, sulfur oxides, nitrogen oxides and is then compressed or liquefied in order to be prepared for "disposal". However, if such a pure carbon dioxide is used to produce gas fuel, its calorific value will be significant due to the absence of the dilution of other gases. This, however, not always turns out to be economical.
• the calorific value of carbon monoxide, when diluted with nitrogen, is about 800-1000 kkal/m 3 gas.
• the calorific value of synthesis gas is about 2400-2600 kkal/m 3 .
• Methane may be admixed to the final ordinary or synthesis gas or may participate in the production of combustible gases, if added to the reacting gases in the reactor. Obviously in this case the calorific value of the newly produced gas will be increased depending on the amount of the supplied methane. For this case the following reactions are valid.
• the pulse intensifying effect is achieved with gaseous medium pulsators (for example paddle pulsators - not shown in Figures) and the acoustic is implemented with acoustic generators with wide frequency spectrum (for example pneumatic horns, not shown in Figures). These intensifying means are mounted near the inlet of gases in the reactors. The intensity of these technical means is determined depending on the size of the reactors, so that the energy of the pulses and the acoustics can be sufficient for the treatment of the whole volume of the reactors.
• the pulse and sound effects help the quick and even homogenization of the gas mixture, which is a condition for the acceleration of the proceeding of the chemical reactions.
• the device for implementing the method is a reactor (1) with chamber, which is filled with carbon solid carrier.
• the chamber can be with high-temperature gas medium (plasma), with needle cathode (3) and flat anode (6), connected to high voltage system (2).

• the device has a rotating plate (5), mounted in the inlet pipe (4), located in the lower part of the reactor (1), which serves to interrupt periodically the gas flow in order to generate pulse effect.
• the outlet pipe is located (7) for CO + H 2 .
• the required for the reactions temperature of 800 °C to 1000 °C is achieved either by external or by integrated in the walls of the reactor heater, not shown in the Figures enclosed.
