‌I. Project Overview‌
The 150,000-ton-per-year PDO/PTT integrated facility of Ningbo Juhua Chemical Technology Co., Ltd. has recently completed trial production and successfully produced its first batch of qualified products. The facility achieved a one-time successful startup. As a key project under Zhejiang Province's "Thousand Projects and Trillion Investment" initiative, its smooth commissioning marks a significant technological breakthrough in China's polyester new materials sector, laying a solid foundation for achieving full domestic industrial chain localization.

‌II. Technical Background‌
Polytrimethylene terephthalate (PTT), as a high-performance polyester material, is widely used in high-end textiles, engineering plastics, and other fields due to its excellent elasticity, dyeing properties, and biodegradability. However, the production technology of its core raw material, 1,3-propanediol (PDO), has long been constrained by foreign monopolies, severely impacting the development of related industries in China.

‌III. Technological Innovation‌
Ningbo Juhua has adopted an innovative technology route with independent intellectual property rights:

‌Technology Route‌: Chemical synthesis method based on ethylene hydroformylation process
‌Core Breakthrough‌: The world's first industrial application of single-atom catalysts
‌Technical Advantages‌: Compared with traditional biological fermentation methods, this technology offers significant characteristics such as stable process, strong raw material supply security, and optimized production costs
‌IV. Strategic Significance‌
The successful implementation of this project holds the following important strategic significance:

‌Ensuring Industrial Chain Security‌: Achieving independent supply of PDO raw materials, effectively enhancing the stability and security of China's high-end materials industrial chain
Enhancing Market Competitiveness: Breaking foreign technology monopolies and bringing raw material prices back to a reasonable range
Promoting Industrial Upgrading: Providing reliable raw material guarantees for downstream application fields and promoting high-quality industrial development
Shijiazhuang Feizi Chemical Technology Co., Ltd. hereby extends its congratulations to Ningbo Juhua Group. The successful commissioning of this project fully demonstrates the technological innovation capabilities of China's chemical enterprises, setting an exemplary model for the integration of industrial technological breakthroughs and industrialization. We look forward to joining hands with industry peers in promoting the autonomy of core chemical technologies to create a brilliant future together.
