Method for production of spherical molded product containing titanium oxide |
摘要 |
A method for the production of a spherical molded product of a titanium oxide composition comprising adding a titanium oxide composition powder and a mist of an aqueous medium to a seed of an inorganic substance, granulating the mixture with a centrifugal fluidizing coating granulator and calcining the resultant spherical product, which is characteristic in that the granulation of the mixture is carried out by adding the titanium oxide composition powder and the aqueous medium in the ratio of addition rate of 1:0.20 to 1:0.35 by weight, whereby there is obtained a spherical molded product having a larger strength with less abrasion. The spherical molded product obtained by the present invention is useful, for instance, as a catalyst carrier or catalyst for the removal of nitrogen oxides from exhaust gases.
