摘要： PROBLEM TO BE SOLVED: To provide a needle-like ceramic body comprised of a cordierite porous body that is stable at high temperatures and has a large specific surface area as a base material and a needle-like ceramic catalyst body and a method for producing the same. SOLUTION: The needle-shaped ceramic body comprises the cordierite porous body that is composed of a porous structure of prescribed porosity formed with needle-like cordierite crystal phase and is stable at the high temperatures and has the large specific surface area as the base material. The needle-shaped ceramic catalyst body is formed by supporting a catalyst component on the ceramic body. By using the porous cordierite composed of needle-like crystals as a catalyst-supporting honeycomb structure, a decrease in the specific surface area caused by sintering can be suppressed. Since a honeycomb structure can be directly produced from a cordierite sintered body by itself, a low-cost product can be obtained by omitting a step for coating the inside of the honeycomb structure in the conventional process.

摘要翻译：要解决的问题：提供一种由在高温下稳定且具有大比表面积的堇青石多孔体构成的针状陶瓷体作为基材和针状陶瓷催化剂体以及方法为了生产相同。解决方案：针状陶瓷体包括堇青石多孔体，其由具有针状堇青石结晶相的规定孔隙的多孔结构构成，在高温下稳定，比表面积大基材。针状陶瓷催化剂体通过在陶瓷体上负载催化剂成分而形成。通过使用由针状晶体构成的多孔堇青石作为催化剂负载蜂窝结构体，可以抑制由烧结引起的比表面积的降低。由于蜂窝结构体可以由堇青石烧结体本身直接制造，所以通过省略在常规方法中涂覆蜂窝结构体的内部的步骤，可以获得低成本的产品。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a carbon dioxide absorbent which can efficiently catch carbon dioxide at high temperature, and to provide a method for separating carbon dioxide.
SOLUTION: This carbon dioxide absorbent is characterized by comprising calcium carbonate and sodium bicarbonate in a calcium : sodium atom ratio of 1 : ≤1 and giving the mixture of the calcium carbonate with the sodium-calcium double carbonate salt having a sodium : calcium ratio of 1 : 1 at high temperature. The carbon dioxide absorbent has an action for catching the carbon dioxide in a high temperature gas exhausted from a coal gasification furnace or the like in a temperature range of 800 to 1,000°C by the absorption and release of the carbon dioxide in the melted state of the double carbonate salt. Herein, the sintering and evaporation of calcia at high temperature after the release of carbon dioxide can be prevented, because the calcium carbonate is taken into the fused liquid of the double carbonate salt.
