TITANIUM DIOXIDE OF ULTRAFINE GRADE FOR SCR DENITIFICATION CATALYST

Titanium Dioxide of Anatase for SCR Denitrification Catalyst

         Selective Catalytic Reduction SCR is the mainstream technology of reducing the nitrogen oxide emissions from thermal power plant, refuse incinerator and automobile exhaust, and catalyst is the core component of SCR system. The TiO2 as carrier of active component should be Anatase crystal structure, high surface area, small grain size (Nano grade) and strong resistance to sulfur dioxide. The SCR Catalyst TiO2 developed by us has stable crystal structure, strong dispersion, powerful adsorption and high resistance to sulfur dioxide. The quality index meets the market needs and is leading the domestic sale and prevailing in the worldwide. Chongqing Xinhua Chemical Co., ltd. as the first producer of denitrification catalyst TiO2 in China has accumulated rich working experience, could produce the SCR denitrification catalyst TiO2 from  different technology resource and different production process: pure titanium powder C-801、titanium with silica powder C-801(G) 、titanium with tungsten C-802、high BET titanium powder C-803、titanium powder with tungsten & silica and catalyst for automobile.
