| titleOfInvention | Manufacturing method of high density titanium dioxide powder for denitrification catalyst |
| abstract | Nitrogen oxides (NOx) are emitted not only from industrial processes such as energy combustion or heating furnaces, but also from high-temperature combustion reactions such as waste incinerators.In order to reduce this, the selective catalytic reduction (SCR) method Is being used. Ceramic honeycomb-type catalysts are mainly used as the catalysts, which are formed of honeycomb powder, dried and calcined products, and the catalyst raw material powder is mostly composed of nano-sized titanium dioxide. The ceramic honeycomb catalyst has a cell density of 11 to 45 cpsi, and the cell density selection is different due to the characteristics of the fuel and the place of combustion. In the present invention, the cell density is higher than 35 cpsi, the cell density of which is reduced in strength due to the thin cell thickness. In the preparation of the honeycomb type catalyst, it is intended to produce nano-sized titanium dioxide that can further increase the mechanical strength and nitrogen oxide removal efficiency is reduced. The present invention is divided into a process of dissolving ore in sulfuric acid, concentrating and hydrolyzing, washing with water, drying and firing, and in particular, increasing the density of raw materials by controlling the conditions of the hydrolysis process and the firing process. To improve the strength, and to provide a nano-sized titanium dioxide production method that can maximize the denitrification performance through pore control. |
