摘要： PURPOSE:To judge the propriety of baking conditions easily by a method wherein an artificial lightweight aggregate baked is cooled with a suction of water after heated at 90-100 deg.C for 3-7 min. and a specific gravity and water absorption ratio are calculated by measuring the weight thereof to evaluate quality thereof in a short time. CONSTITUTION:An artificial lightweight aggregate based with a baking furnace is immersed into water to cool immediately after heated at 90-100 deg.C for 3-7 min. After the cooling, the weight of the artificial aggregate is measured and a specific gravity and a water absorption factor are calculated to judge quality thereof in a short time. Thus, the propriety of baking conditions during a baking at the present is judged in a short time and the baking conditions are controlled thereby preventing the generation of a defective product.

摘要： PURPOSE:To enable production of a calcined article suitable as a carrier or a catalyst, having large surface area, excellent heat resistance and excellent strength after molding, by adding silicic acid fine particles to titanium sulfate and thermally hydrolyzing. CONSTITUTION:Silicic acid fine powder having extremely high specific surface area, known as white carbon of another name, is added to an aqueous solution of titanium sulfate. The mixture is thermally hydrolyzed to form metatitanic acid, which is precipitated together with the silicic acid fine powder. In the operation, the thermal hydrolysis of titanium sulfate is carried out by heating the aqueous solution of titanium sulfate containing the silicic acid fine powder usually to 80 deg.C- the boiling point thereof, preferably to the boiling point and more preferably in the presence of seed crystal to shorten time required. Since metatitanic acid formed by the thermal hydrolysis is gelatinous state, metatitanic acid is partially or wholly made into sol, washed, filtered, dried, calcined at

摘要： PURPOSE:To enhance adsorption capacity of H2S by carbonating the secondary particles of calcium silicate being hollow and rough under the coexistence of water content, and converting them into amorphous silica and calcium carbonate, and thereafter acid-treating them to form a desulfurizing agent. CONSTITUTION:The secondary particles of calcium silicate having about 10-150mum diameter wherein primary particles are interlocked and formed irregularly and three-dimensionally and the inside is made hollow or rough are subjected to carbonating treatment under the coexistence of water content and converted into amorphous silica and calcium carbonate. Then a desulfurizing agent which has amorphous silica maintaining the secondary-particle shape of calcium silicate as a carrier is obtained by performing acid-treatment. This amorphous silica is excellent in molding performance and can be molded into a granular shape, a honeycomb shape and a columnar shape, etc., by extrusion molding. In this molded form, micropores are formed and the adsorbing reaction of H2S is effectively advanced.

摘要： PURPOSE:To reduce the oxidizing capacity for SO2 of the titled catalyst without deteriorating the denitrating capacity by dipping a kneaded forming body consisting of TiO2 and WO3 into an acidic soln., semi-drying, and then further dipping in an alkaline soln contg. V, drying and calcining. CONSTITUTION:The kneaded forming body consisting of TiO2 and WO3 is dipped in the acidic soln. and then a part of moisture existing in the neighborhood of the surface of the forming body is removed by air-drying or air-drying together with hot-air drying. Then, it is dipped in an amine soln. of vanadium and V2O5 is held in the neighborhood of the surface layer of the forming body by the neutralizing reaction of acid and alkali. The catalyst for denitration consisting of 2-12wt% WO3 with respect to TiO2, 0.1-3wt% V2O5 with respect to TiO2 and the balance TiO2 is prepared by drying and calcining. The oxidizing capacity of SO2 is sufficiently reduced without deteriorating the denitrating capacity by simply raising the concentration of V2O5 held in the surface layer.

摘要： PURPOSE:The adsorbent which has adsorbed sulfur is roasted with air or oxygen partially containing a high-temperature reducing gas to suppress the oxidation degree of the metal oxides in the regenerated adsorbent whereby repeated used of the adsorbent is made possible. CONSTITUTION:When the adsorbent of oxides of metals such as Fe, Zn or Mo filled in the reactor 7 is almost saturated with sulfur compounds in the high-temperature reducing gas, a gas containing oxygen and/or air 13 and a part of the reducing gas free from coarse dust 6 is fed to regenerate the adsorbent by roasting and obtain a sulfur dioxide gas 16 of the high concentration. EFFECT:High-efficiency removal of sulfur compounds can be done without reduction of energy sources such as carbon monoxide or hydrogen in the high- temperature reducing gas.

摘要： PURPOSE:To facilitate the handling of a reducing agent in the storage and transport thereof, by performing selective colalytic reductive denitration by using NH4Cl as a reducing agent. CONSTITUTION:The exhaust gas 2 generated from a boiler 1 is passed through the catalyst 4 allowed to pack a denitration apparatus 3 along with NH3 generated by thermally decomposing an aqueous NH4Cl solution, which is supplied to an injection line 10 from a storage tank 8 by a quantitative pump 9 while receives the control of an injection amount, to be denitrated and the exhaust gas after denitration is heat-exchanged by an air heater 6 to be transferred to the downstream machinery. The effect of NH4Cl to denitration reaction is not different from that of NH3 and handling in storage and transport becomes easy.

摘要： PURPOSE: To obtain a carbon monoxide converting catalyst having high activity and enhanced durability, by supporting catalytic components based on iron and chromium by a carrier comprising porous heat resistant zeolite.
CONSTITUTION: A honeycomb like or hollow cylindrical porous heat resistant zeolite carrier is immersed in a liquid mixture containing iron nitrate and chromium nitrate and the impregnated carrier is baked at 200W350°C to prepare a carbon monoxide converting catalyst. As the aforementioned zeolite, not only a natural product but also a synthetic one such as Y type or A-type zeolite different in a crystal structure can be used and, to the molding thereof, technique such as the extrusion molding of a honeycomb shape or the lamination molding by a corrugate machine can be adapted. As the method for supporting the catalytic components, a method, wherein a zeolite carrier is immersed in a solution of iron nitrate and chromium nitrate to support both nitrates and the impregnated carrier is immersed in aqueous ammonia in a wet state, can be adapted.
