摘要： A process for the direct reduction of iron oxide by blowing into a reduction furnace a reducing gas which is prepared by reforming a mixture of a reduction furnace exhaust gas and a gas mainly composed of methane, which comprises the steps of dividing the gas mainly composed of methane into two branch streams, mixing the first branch stream gas with a part of the reduction furnace exhaust gas and supplying the resulting mixture to the externally heated reformer furnace, to produce a high-temperature reformed gas; mixing the second branch stream gas with said high-temperature reformed gas and during the course to the reduction furnace, subjecting the mixture to endothermic reforming reactions in an after-reactor without external heating, utilizing the sensible heat of the high-temperature mixed gas, controlling the self-reforming reactions so as to lower the temperature and simultaneously adjust the composition of the high-temperature mixed gas, and blowing the reducing gas obtained into the reduction furnace. Effective use of the sensible heat can be achieved.

摘要： The present invention relates to a catalyst to be used for catalytically reducing nitrogen oxides contained in a combustion exhaust gas discharged from a calcination furnace, a coking furnace or a boiler or an exhaust gas from a nitric acidpreparing plant in the presence of a reducing gas such as ammonia to convert the nitrogen oxides to harmless substances, and to a method for converting these nitrogen oxides by using this catalyst. According to the present invention, in the presence of a catalyst consisting essentially of oxides or organic or inorganic compounds of V and Nb or V, Nb and at least one element selected from the group consisting of Cu, Ti, Fe, Cr, W, Mo and Ni, which are supported on a carrier, a reducing gas such as ammonia is incorporated in an exhaust gas, and nitrogen oxides in the exhaust gas are catalytically reduced and converted to harmless substances. The catalyst of the present invention is not deactivated by other components contained in the exhaust gas, such as sulfurous acid gas, water and the like, and a very high conversion of nitrogen oxides can be attained not only in the high temperature range but also in the low temperature range.

摘要： A catalytic combustion apparatus has a cylindrical housing defining a fluid passage, and a plurality of combustion catalyst bodies arranged face to face along the fluid passage in the cylindrical housing. The catalyst bodies are loosely fitted in the cylindrical housing. Each catalyst body defines numerous bores extending along the fluid passage. The cylindrical housing includes holders extending inwardly of the housing for contacting end surfaces of the catalyst bodies to prevent movement thereof along the fluid passage.

摘要： PURPOSE:To restrain the stress concentration due to thermal strain, etc., by a method wherein combustion catalyst layers are formed into a shape having partly cut-off segment cross section horizontal to the flow path direction, and the combustion catalyst layers are piled up in such a manner that the adjacent combustion catalyst layers in the flow path direction compensate the cut-off sections each other. CONSTITUTION:A preheating combustion chamber 1, a lean fuel gas mixing chamber 2, a cylindrical catalytic combustion chamber 3 and a combustion gas exhaust part 4 are arranged in sequence along the combustion gas flow path, and combustion catalyst layers 5 consisting of honeycomb catalysts each having a large number of through- holes are arranged along two or more flow paths. The catalyst layers 5 are formed in a shape having partly cut-off segment section horizontal to the flow path direction, and arranged in staggered rows in the flow path direction so that the adjacent catalyst layers compensate the cut-off segmental parts each other and those edges overlap so as to cover the whole section. Those two or more catalyst layers 5 are piled and held from the front and back and clearances are provided between the catalyst layers 5, preventing an increase in draft resistance and generation of local thermal strain.
