摘要： PURPOSE:To enable production of titanium oxide calcined product having large surface area and excellent heat resistance as well as excellent strength after molding and suitable as a carrier or catalyst, by calcining solated metatitanic acid containing fine-particle silicic acid. CONSTITUTION:A fine-particle silicic acid known also as white carbon of another name and having extremely large specific surface area is added to metatitanic acid sol and mixed while stirring and the mixture is then calcined. As necessary, after fine-particle silicic acid is added to metatitanic acid, the metatitanic acid may be solated. Fine-particle silicic acid can be more uniformly dispersed into metatitanic acid by solation, because metatitanic acid is gel-form. A mixed of metatitanic acid obtained thus and fine-particle silicic acid is washed with water and then calcined at about

摘要： PURPOSE:To inhibit the growth of titanium oxide crystals and to obtain a calcined product having superior heat resistance and mechanical strength by adding a W compd. and/or an Mo compd. to metatitanic acid converted into sol. CONSTITUTION:A W compd. and/or an Mo compd. is used as an additive. This additive is added to metatitanic acid converted into sol and the metatitanic acid is calcined. During the calcination the growth of titanium oxide crystals is inhibited and the crystals remain as ungrown anatase type crystals, so the heat resistance and mechanical strength of a calcined product are improved.

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： PROBLEM TO BE SOLVED: To convert carbonyl sulfide having numbers of base points into hydrogen sulfide by hydrolysis by adding a metal sulfate or a metal carbonate as a cocatalyst to anatase type titanium.
SOLUTION: As a method for highly activating a TiO
2 carrier, the addition of a cocatalyst is considered. The addition of a metal sulfate and a metal carbonate as a substance of a stable structure is considered. Besides, conversion into a complex oxide is cited to improve the performance of the TiO
2 carrier. In general, by the conversion of a metal oxide into a complex metal oxide, the specific surface area increases, and also the heat resistance is improved. Also, solid base points increase. Although the form of a catalyst used in this reaction is not specified, a honeycomb-shaped catalyst is preferable. This catalyst added with a cocatalyst is prepared by a method in which metatitanic acid or titania, a metal sulfate, and a metal carbonate are added, and the mixture is added with a binder, kneaded, molded into a honeycomb, dried, and baked.

摘要： PURPOSE:To sufficiently carry out the sintering and readily obtain an artificial aggregate at a low cost by mixing coal ash with a low unburned carbon content with heavy oil ash, increasing the carbon content, then granulating the mixture and sintering the granulated mixture. CONSTITUTION:Heavy oil ash discharged from a heavy oil burning boiler is mixed with coal ash discharged from a coal burning boiler. Since the heavy oil ash contains unburned carbon and combustibility is excellent with a low bulk specific gravity, the unburned carbon content is a required carbon content (>=4wt.%) and the self-combustion of the granulated mixture is carried out in sintering thereof to perform sufficient sintering.
