摘要： There is provided a method for recycling a catalyst that exhibits a high denitration efficiency at a relatively low temperature and does not cause oxidation of SO2 in a selective catalytic reduction reaction that uses ammonia as a reducing agent. A method for recycling a denitration catalyst includes a step of removing a used denitration catalyst from a denitration device and then coating the used denitration catalyst with a catalyst component. The catalyst component contains 43 wt % or more of vanadium pentoxide and has a BET specific surface area of 30 m2/g or more, and the denitration catalyst after recycling is used for denitration at 200° C. or lower.

摘要： A finger mechanism for a robot, an artificial hand, and the like, wherein a fourth bone member (14) of the bone members of the finger mechanism and corresponding to the distal phalanx comprises: a support portion (15) that is rotatably coupled to a third bone member corresponding to the middle phalanx by a rotational shaft (g5); and a nail portion (16). The nail portion (16) can freely rotate about a shaft (g7) at a right angle or a near right angle to the rotational shaft (g5), and a return mechanism (17) to return the rotated nail portion (16) to a reference position is provided between the support portion (15) and the nail portion (16). In this manner, in response to the amount of force applied to the fourth bone member (14), it is possible for only the nail portion (16) to rotate in a direction to easily grasp an object to be held.

摘要： A combustion system operated at low cost is provided. A combustion system 1 includes a combustion device 10 that burns fuel, an exhaust line L1 through which exhaust gas flows, the exhaust gas being generated through combustion of the fuel in the combustion device 10, a dust collector 50 that is disposed in the exhaust line L1 and that collects dust in the exhaust gas, and a denitration device 90 that is disposed in the exhaust line L1 and that removes nitrogen oxide from the exhaust gas using a denitration catalyst. The denitration device 90 is disposed downstream from the dust collector 50 in the exhaust line L1.

摘要： A method for manufacturing, a secondary battery separator including a porous resin film in which pores have three-dimensionally ordered structure and are in mutual communication via through-holes. The method includes: uniformly dispersing spherical microparticles having narrow particle size distribution in a dispersion medium to prepare a microparticles-dispersed slurry; drying slurry to obtain a spherical microparticles-dispersed film; heat-treating the film to form a microparticles-resin film in which the microparticles are regularly arrayed in three-dimensions in a resin matrix; and contacting the microparticles-resin film with an organic acid, water, an alkaline solution or an inorganic acid other than hydrofluoric acid to dissolve and remove the microparticles, or heating the microparticles-resin film to remove the microparticles, to form pores which are in mutual communication and regularly arrayed in the resin matrix. The medium has a resin precursor for the resin matrix and surfaces of the microparticles are inactive against the medium.

摘要： There is provided a method for recycling a catalyst that exhibits a high denitration efficiency at a relatively low temperature and does not cause oxidation of SO2 in a selective catalytic reduction reaction that uses ammonia as a reducing agent. A method for recycling a denitration catalyst includes a step of spraying an aqueous solution with a pH of 7 or more onto a used denitration catalyst while the denitration catalyst is set in a denitration device to remove a surface of the denitration catalyst. The denitration catalyst contains 43 wt % or more of vanadium pentoxide and has a BET specific surface area of 30 m2/g or more. The denitration catalyst after recycling is used for denitration at 200° C. or lower.
