摘要： This invention provides a method for producing a ceramic catalyst body that can directly support a catalyst on a ceramic support without disposing a coating layer on the ceramic support. In the invention, a catalyst solution containing a catalyst component consisting of a negative complex ion resulting from a catalyst precursor is prepared, and a pH of the catalyst solution is adjusted in such a manner as to satisfy the relation E1>E2 and E1>0 where E1 is a surface potential of a matrix phase consisting of a cordierite-W composite body relative to the pH of the catalyst solution and E2 is a surface potential of a dispersed phase consisting of compounds other than the cordierite-W composite body. After the ceramic support is brought into contact with the catalyst solution to support the catalyst component, heat-treatment is conducted to bond the matrix phase consisting of the cordierite-W composite body and the catalyst component to support the catalyst on the ceramic support.

摘要： This invention aims at achieving early activation by use of a catalytic body having a low thermal capacity, and a low pressure loss, without using a coating layer to reduce exhaust emission. The invention is directed also to improve exhaust purification performance by improving the combination of catalytic bodies and performance of each catalytic body. In the invention, a start catalyst 1 is arranged at an upstream portion of an exhaust pipe P of a car engine E and a three way catalyst 2 is disposed on the downstream side. The start catalyst 1 can directly support catalytic components through chemical bonds by incorporating replacing elements into a substrate ceramic having high heat resistance such as cordierite. Because a coating layer is not necessary, the catalyst of the invention has a low heat capacity and a large open area and achieves reduction of exhaust emission, and reduction of a pressure loss, through early activation.

摘要： A carbon-based combustion catalyst is obtained by performing a burning step of burning sodalite at a temperature of 600° C. or more. Alternatively, a carbon-based combustion catalyst is obtained by performing the following mixing step, drying step, and burning step. In the mixing step, aluminosilicate (sodalite), and an alkali metal source, and/or an alkaline earth metal source are mixed in water to obtain a liquid mixture. In the drying step, the liquid mixture is heated to evaporate the water thereby obtaining a solid. In the burning step, the solid is burned at a temperature of 600° C. or more. The thus-obtained catalyst can cause carbon-based material to be stably burned and removed at a low temperature for a long time.

摘要： A carbon-based material combustion catalyst is manufactured by performing a mixing step, a drying step, and a burning step. In the mixing step, zeolite except for sodalite, an alkali metal source, and/or an alkaline earth metal source are mixed in water at a predetermined ratio. In the drying step, a liquid mixture after the mixing step is heated to evaporate the water, thereby obtaining a solid. In the burning step, the solid is burned at a temperature of 600° C. or more. The obtained carbon-based material combustion catalyst causes carbon-based material to be stably burned and removed at a low temperature for a long time.
