Abstract: PROBLEM TO BE SOLVED: To efficiently produce hydrogarnet in a simple process by carrying out a hydrothermal treatment of a mixture of a silica source with an alumina source and a calcium source. SOLUTION: Kaolin, silica, amorphous silica, diatomaceous earth, silica sand, quartz, etc., are cited as a silica source. Kaolin, an alumina sol, boehmite, aluminum hydroxide, aluminum oxide, etc., are cited as an alumina source. Quick lime, slaked lime, gypsum, etc., are cited as a calcium source. The raw materials are mixed in a prescribed proportion and water in an adequate amount is subsequently added thereto. The resultant mixture is then subjected to a hydrothermal treatment which is preferably carried out at 130-200 deg.C hydrothermal treating temperature for about 15 h hydrothermal treating time by using, e.g. an autoclave. The resultant hydrogarnet has a high heat-resistant temperature and is capable of efficiently absorbing and fixing an acidic waste gas at a high temperature up to about 1,000 deg.C.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an adsorbent for a high temperature acidic exhaust gas and a method for removing a high temperature acidic gas. SOLUTION: In the absorbent for exhaust gas, a mixture of amorphous calcium silicate hydrate and sodium aluminate is subjected to hydrothermal treatment. In the method for removing exhaust gas, a high temperature acidic exhaust gas discharged from an incinerator and others is absorbed/fixed by the absorbent. In this way, the adsorbent for an acidic exhaust gas can be produced efficiently by a simple process. The adsorbent is useful as a fixing agent for fixing/absorbing a high temperature acidic exhaust gas discharged from the incinerator and others.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a porous wall material, in which molding and solidifying are conducted without reducing the steam absorption of porous powder having no moldability and which displays an autonomous humidity-conditioning function. SOLUTION: A porous wall material combining hygroscopicity and moisture absorption characteristics without damaging porosity and having pores in nanometer order is manufactured by preparing and drying molded and solidified forms by utilizing the viscosity of a silica sol. Accordingly, a functional material autonomically having a humidity-conditioning function can be supplied without imparting energy from the outside by a capillary condensation phenomenon generated in pores in nanometer order by providing an energy-conservative porous solidified-form manufacture as a molding method making the strength of porous powder having no moldability and steam absorption coexist.
