    摘要： The composite oxide and the composite oxide carrier are manufactured by the precursor forming step and firing step. The precursor forming step includes high speed mixing means. The composite oxide catalyst is obtained by preparing a composite of catalytic components simultaneously with the formation of the precursor of composite oxide in the step of forming the precursor of composite oxide. The composite oxide and the composite oxide carrier are composed of a composite oxide in which at least one of cerium and zirconium, and aluminium disperse with extremely high homogeneity. With this structure, the heat resistance of the carrier is improved and consequently, enlargement of particles of the composite oxide defining the carrier, and sintering of adjacent particles of the composite oxide can be restrained, whereby the catalyst using the composite oxide carrier in accordance with the present invention is excellent in heat resistance. With the present invention, the carrier is not limited to a general catalyst carrier. The carrier may be interpreted to indicate general formed bodies. For example, the carrier with the present invention can be also used as materials for sensors and electrodes, optical materials, semiconductors and structure materials. Furthermore, the carrier can be used for a three-way catalyst, NOx catalyst or oxidation catalyst or a part thereof, and a promoter.

    摘要： A composite oxide includes CeO2, ZrO2 and a metallic oxide being free from reacting with CeO2 and ZrO2 at 700° C. or more, preferably at 900° C. or more and further preferably at 1,000° C. or more. The composite oxide has a regulatory oriented phase, such as a pyrochlore phase, etc., in which at least a part of Ce cations and Zr cations are oriented regularly. The composite oxide makes a catalytic support. The CeO2—ZrO2 composite oxide and the reaction-free metallic oxide make barriers each other which suppress the granular growth when the composite oxide is subjected to high-temperature heat in a reducing heat treatment to form the regulatory oriented phase. The regulatory oriented phase improves the oxygen storage-and-release capability of the catalytic support. Thus, it is possible to simultaneously attain a large a specific surface area and a high oxygen storage-and-release capability.

    摘要： A metal oxide which has a large pore volume, and is very useful as a catalyst support. An alkaline material is added to an aqueous solution in which a compound of a metal element for composing an oxide is dissolved, a resultant mixture is co-precipitated, an obtained precipitate is washed, a washed precipitate is stirred in water along with a surfactant, and is calcined. By adding the surfactant after washing, the pH is not changed so that the adding effect of the surfactant is achieved to its upper most limit, thereby obtaining a metal oxide which has a large pore volume and a large mean diameter of secondary particles, and exhibits excellent gas diffusion properties.

The first reaction vessel is hermetically connected to the receptacle and supplied with water from the receptacle. The first reaction vessel contains a chemical compound that causes a hydration reaction with the water from the receptacle to generate water vapor by a heat of reaction, and causes a dehydration reaction by receiving heat. The second reaction vessel is hermetically connected to the first reaction vessel and supplied with the water vapor from the first reaction vessel. The second reaction vessel contains a chemical heat storage material that generates heat by causing a hydration reaction with the water vapor from the first reaction vessel and stores heat through a dehydration reaction caused by receiving heat.
