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 improve preservation of environment and workability without discharging harmful substance in the atmosphere by returning gas after combustion which contains NOx and SOx discharged from a calciner of granulated material to the front flow side of a denitrification equipment for a coal burning boiler. CONSTITUTION:Granulated fly ash material discharged from a granulating molding machine 19 is carried to a calciner 21 having a plurality of combustion zones separated from the atmosphere. The gas 22 after calcination containing NOx and SOx is circulated to the flue in the inlet of a denitration equipment 5 for a coal burning boiler wherein ammonia 6 is utilized as a reducing agent. The gas treated in the denitrification equipment 5 is passed through an air heater 7 and dusted off in a dust collector 8 and discharged as purified gas after removing SOx in a desulfurization facility 9.
