Founded in July 2024,As China SCR Exhaust Gas Treatment Manufacturers and Wholesale Iron-Based SCR Catalyst 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.
Iron-based SCR (Fe-SCR) catalysts, typically using Fe-Beta zeolites, are designed for high-temperature selective catalytic reduction of NOx in diesel exhaust systems. Fe-SCR catalysts are particularly effective in higher temperature windows, making them suitable for heavy-duty diesel engines and applications where exhaust gas temperatures frequently exceed 350–400°C. The catalyst’s carrier can be ceramic or metal honeycomb structures capable of withstanding high temperatures and corrosive environments.
The coating consists of TiO₂ as the primary support, doped with iron as the active component. This combination ensures excellent thermal stability, wide operational temperature range, and resistance to sulfur poisoning. The Fe-SCR catalyst primarily facilitates the standard SCR reaction (4NH₃ + 4NO + O₂ → 4N₂ + 6H₂O), achieving efficient NOx conversion at elevated temperatures. Its robust design ensures long-term durability, stable performance, and high NOx reduction efficiency, making it ideal for integration in modern diesel after-treatment systems compliant with Euro VI and China VI standards.
