Q1: What is the primary function of Jinmao SCR Denitration Titanium Dioxide in selective catalytic reduction systems?
A: Jinmao SCR Denitration Titanium Dioxide serves as a high-performance support material and functional promoter in SCR catalyst formulations, enhancing thermal stability, surface area retention, and NOx conversion efficiency under demanding flue gas conditions.
Q2: How does this titanium dioxide differ from standard TiO2 pigments used in coatings or plastics?
A: Unlike pigment-grade TiO2, Jinmao SCR Denitration Titanium Dioxide is engineered with controlled crystallinity (predominantly anatase phase), tailored pore structure, and high purity to optimize catalytic activity and resistance to sintering and poisoning in high-temperature denitration applications.
Q3: Is it compatible with common SCR catalyst active components such as vanadium oxide or tungsten oxide?
A: Yes — Jinmao SCR Denitration Titanium Dioxide is specifically developed as a robust carrier for V2O5, WO3, and other transition metal oxides, offering strong metal-support interaction and uniform dispersion to improve catalyst durability and low-temperature NOx removal performance.
Q4: What are key handling and storage recommendations to maintain its performance integrity?
A: Store in a cool, dry, well-ventilated area, protected from moisture, direct sunlight, and airborne contaminants. Avoid prolonged exposure to humid environments prior to catalyst preparation, as excessive moisture may affect surface hydroxyl density and subsequent active component loading.
