As global emission standards shift toward ultra-low and zero-emission targets, the efficiency of industrial gas purification increasingly depends on the kinetic and thermodynamic limits of the reagents used. Conventional bulk materials are no longer sufficient for high-end SCR catalyst manufacturing and deep desulfurization.

As a dedicated supplier of advanced catalytic raw materials, we engineer nano-scale solutions that address both the chemical demands of the reaction and the rigorous logistical requirements of global supply chains.

1. Nano TiO₂ for SCR Catalysts: Extrusion, Washcoating, and Regeneration

In the DeNOx sector, the V₂O₅ - WO₃ / TiO₂ system is the foundational structure for Selective Catalytic Reduction (SCR) catalysts. To meet diverse engineering requirements, we supply our Nano TiO₂ in two meticulously engineered forms:

• Instant Re-dispersible Nano Dry Powder: Designed for the extrusion molding of homogeneous honeycomb SCR catalysts. This dry powder form drastically reduces cross-ocean shipping costs by eliminating water weight and prevents freezing damage during winter transit. Upon mixing at the facility, it achieves secondary dispersion in seconds, eliminating agglomeration issues.
• Stabilized Nano Dispersion Liquid: Formulated specifically for washcoating on cordierite or corrugated substrates, and for micropore restoration during catalyst regeneration. Utilizing proprietary surface modification and steric hindrance technology, our dispersion liquid guarantees zero settling and extreme stability over a 12-month shelf life, ensuring highly homogeneous distribution of active catalytic sites.

2. High-Activity Nano-ZnO: Pushing the Boundaries of Deep Desulfurization

For processes requiring the total elimination of hydrogen sulfide (H₂S)—such as syngas purification and fine chemical refining—we supply High-Activity Nano-Grade Zinc Oxide. While conventional micro-scale ZnO suffers from high diffusion resistance and requires elevated temperatures (200°C - 400°C) to react efficiently, our Nano-ZnO breaks this thermodynamic barrier. Driven by the reaction ZnO + H₂S → ZnS + H₂O, the exponentially increased specific surface area significantly lowers the activation energy. This not only yields an exceptional breakthrough sulfur capacity, reducing sulfur to ppb levels, but also broadens the low-temperature operating window, saving substantial heating energy costs for processing plants.

In the advanced materials supply chain, physical data is as critical as chemical purity. We provide comprehensive analytical reports for all our nanomaterials, including full Certificate of Analysis (COA), third-party Particle Size Distribution (PSD D₅₀/D₉₀) reports, BET surface area data, and SEM/TEM imaging.
