Frequently Asked Questions (FAQs)
What is selective catalytic reduction (SCR) and why is it important?
Selective catalytic reduction (SCR) is a technology used to reduce harmful nitrogen oxide emissions from diesel engines. It involves injecting a urea-based solution into the exhaust system, which reacts with the nitrogen oxides in the presence of a catalyst, converting them into harmless nitrogen and water. This process is crucial for meeting environmental regulations and improving air quality.
Where are the major SCR catalyst factories located in China?
China has several major SCR catalyst factories, primarily located in industrial hubs like Jiangsu, Zhejiang, and Guangdong provinces. These regions are known for their advanced manufacturing capabilities and proximity to key automotive and industrial markets.
What materials are commonly used in SCR catalysts?
SCR catalysts typically use materials like titanium dioxide, vanadium pentoxide, and zeolites. These components help facilitate the chemical reactions needed to convert nitrogen oxides into harmless substances, ensuring the catalysts are effective and durable under high temperatures.
How do I choose a reliable SCR catalyst supplier in China?
When selecting a supplier, consider their experience in the industry, product quality certifications, and customer reviews. It’s also beneficial to request samples and inquire about their manufacturing processes to ensure they meet your specific requirements and standards.
What are the challenges faced by SCR catalyst manufacturers in China?
Manufacturers in China face challenges such as fluctuating raw material prices, stringent environmental regulations, and competition from both domestic and international players. Additionally, keeping up with technological advancements and ensuring product quality can be demanding in this rapidly evolving market.
