Founded in July 2024,As China Copper-Based SCR Catalyst Manufacturers and Wholesale SCR Low Temperature Catalyst System Factory, Longyou Shuochun New Material Technology Co., Ltd. is a high-tech enterprise specializing in the coating and sales of three-way catalytic converters. It is deeply engaged in the field of new materials.
The company always keeps an eye on the industry frontier, actively learns from and draws on the advanced formulas and mature technologies of domestic and foreign counterparts. Through in-depth research and localization of mainstream formulas, it accurately adjusts the proportion of raw materials such as rare earths, precious metals and non-precious metals, so as to ensure that the coated carriers produced have stable catalytic activity and reliable performance.
The company's products cover a variety of specifications and models, and its products and technologies are applicable to automobiles, motorcycles, general-purpose engines, construction machinery, marine power, generator sets, agricultural machinery and other fields.
In the future, the company will continue to learn advanced industry experience, optimize production and services, and contribute to the realization of carbon peaking and carbon neutrality goals in China and around the world.
Copper-based SCR catalysts, particularly Cu-CHA structures such as Cu-SAPO-34 and Cu-SSZ-13, are widely recognized for their superior low-temperature activity and broad temperature operating window. They are especially suitable for modern light-duty and heavy-duty diesel vehicles where stringent Euro VI or China VI emission limits must be met.
The catalyst uses a ceramic or metallic honeycomb carrier with a high-surface-area coating based on TiO₂, in which copper ions are embedded as active components. Cu-SCR catalysts excel in facilitating both the standard SCR (4NH₃ + 4NO + O₂ → 4N₂ + 6H₂O) and fast SCR reactions (2NH₃ + NO + NO₂ → 2N₂ + 3H₂O), ensuring rapid NOx reduction even at temperatures as low as 200°C. With outstanding thermal stability exceeding 650°C, Cu-SCR catalysts can be placed in tight-coupled configurations near the engine, providing highly efficient NOx conversion and resistance to deactivation from sulfur or hydrocarbon exposure.
