摘要： PURPOSE:To obtain a high denitration ratio by preventing the lowering of an average denitration ratio due to the local deviation of molar ratio in a passage area just before a catalyst layer or the discharge of an unreacted NH3. CONSTITUTION:Although NH3 is incorporated as a reducing agent in an exhaust gas passage area upstream from a catalyst layer 1, a catalyst is used which comprises the first component having the activity as the catalyst for reducing nitrogen oxide by NH and the second component having either of the activity of producing NOx from NH3 and the activity of producing CO2 from CO. By using this catalyst, NOx in the exhaust gas is reduced and unreacted NH3 and CO are decomposed simultaneously without being restricted by the local deviation 2 of the molar ratio of NH3/NOx in an exhaust gas passage area just before the catalyst layer. Thus, the exhaust gas treatment is possible even when the local molar ratio of NH3/NOx in the exhaust gas passage area just before the catalyst layer is 1 or more, giving a high denitration ratio, while the decomposition of the unreacted NH3 and the oxidation of CO can be carried out efficiently.

摘要： A method for removing carbon dioxide from a combustion exhaust gas under atmospheric pressure makes use a mixed solution of a specific amine compound X and another amine compound Y being homopiperazine. The amine compound X is an amine compound having one alcoholic hydroxyl group and a tertiary amino group, at least one group bonded to the tertiary amino group having a chain of two or more carbon atoms inclusive of its bonding carbon atom, two of the groups bonded to the tertiary amino group being unsubstituted lower alkyl groups.

摘要： The invention relates to an apparatus for gas-liquid contact comprising tubular structure fillers having straight tubular portions, said tubular structure fillers arranged in a substantially vertical direction in the form of plural steps within the apparatus so that the gas-liquid contact surfaces of the fillers are parallel with the flow of the gas, whereby the gas is brought into contact with the liquid by feeding the liquid from a site above the fillers, allowing the liquid to flow downwardly along the filler surfaces, and feeding the gas from a site under the fillers. Said apparatus being characterized in that the gas-liquid contact surfaces of the fillers (2) comprise a rough surface portion having a center line average height of 50 mu m or more, or a porous surface portion having a plurality of orifices (2a), or a mesh and said apparatus being characterized in that said plural steps of the fillers (2) are separaten from each other, and there is interposed, between the steps, a dispersing plate.

摘要： A method for recovering carbon dioxide gas present in combustion exhaust gas. More specifically, the present invention solves problems associated with the absorption of carbon dioxide from combustion exhaust gas using a monoethanolamine solution. First, with the provision of storage units for the monoethanolamine solution which has absorbed carbon dioxide and for the monoethanolamine solution which has been regenerated, variations in power demand at power generation facilities are utilized effectively. Also, provided is a method of recovering carbon dioxide wherein a monoethanolamine solution is made inflammable. Further, the optimization of exhaust gas from which carbon dioxide is recovered is achieved.
