Abstract: A method for preparing an active catalyst for high-efficiency denitration is disclosed. The method includes: a catalyst raw material is charged into a denitration reactor, NH3 and an inert gas are introduced and then heating is performed, and the temperature is held and then natural cooling is performed, thereby obtaining the catalyst. The active catalyst can greatly improve the denitration activity in low temperature range, and can not only improve the denitration efficiency under the condition without SO2 and H2O, but also can improve the denitration efficiency under the condition with both SO2 and H2O. The service life of the catalyst is prolonged under the premise of not changing the existing catalyst preparation process, and the economic benefit is significant. The denitration efficiency of a powder catalyst can be increased by 25%, and the denitration efficiency of a honeycombed catalyst or a corrugated catalyst can be increased by 20%.

Abstract: A method of manufacturing an electrically heated catalyst device includes preparation of a metal thin plate as a material of a metal electrode layer. The metal thin plate includes wiring portions, a base, a terminal portion, a second base, and a pseudo terminal portion. The method includes supplying current between the terminal portion and the pseudo terminal portion of the metal thin plate after fixing layers are formed; and forming the metal electrode layer by removing a portion of the metal thin plate between a smallest cross-sectional area portion and a distal end of the pseudo terminal portion through melting and cutting of the smallest cross-sectional area portion using the Joule heat generated by the supplied current. The smallest cross-sectional area portion is a part of the metal thin plate that has a smallest area in a cross section perpendicular to the extending direction of the wiring portions.

Abstract: A porous ceramic structure with low pressure loss and high catalytic performance is provided. The porous ceramic structure includes a porous structure body (i.e., honeycomb structure) composed primarily of cordierite, and manganese (Mn) and tungsten (W) that are fixedly attached to the honeycomb structure. Thus, pressure loss in the porous ceramic structure can be reduced, and an NO combustion temperature in the porous ceramic structure can be lowered. In other words, the aforementioned structure of the porous ceramic structure allows the porous ceramic structure to have low pressure loss and high catalytic performance.
