(JP6071134-A)      Appts. for removing carbon dioxide contained in exhaust gas comprises (a) a hydrogen supply appts. for supplying a hydrogen source; (b) a mixer for uniformly mixing the hydrogen source supplied from the hydrogen supply appts. with exhaust gas contg. carbon dioxide to form mixed gas; (c) a beam generator for generating high energy beams; (d) a reaction container for activating the mixed gas by irradiating high energy beams from the beam generator and for causing reduction reaction of the carbon dioxide; and (e) a recovery section for separating a prod. formed by the redn. reaction from the exhaust gas and recovering the prod.    Also claimed is a method of removing carbon dioxide contd. in exhaust gas.    The hydrogen source is one type of gas chosen from hydrogen, methane, ethane, ethylene, acetylene or water, in which the high energy beams are electron beams of 100 KV or above, or laser beams of wavelength 500 microns or lower. The beam generator is a beam deflector for the high energy irradiation. Solid and liquid prods. are recovered in the recovery section which is an electric dust collector. The reaction container has many layers of metallic wire mesh, such as stainless steel, the wires being grit blasted or ceramic coated, causing surface irregularities, the mesh aperture being no less than 0.3mm. At least one type of filler chosen from a porous member, a foaming member, a honeycomb or a fin is disposed within the reaction container to promote the reduction reaction. The cross-sectional area of the reaction container is gradually decreased in the direction of flow of the mixed gas.    USE/ADVANTAGE -   Carbon dioxide is removed from exhaust gas at a high reaction speed under the conditions of temp. and pressure of the exhaust gas itself without needing to heat or pressurise an amount of exhaust gas discharged from thermal power plants, the reaction prods. finding use industrially.
