Yanshan Petrochemical: Building a leading industry-based production facility for clean aviation fuel. Recently, with a clear whistle, a specialized tank truck loaded with 100VLL aviation gasoline slowly left the factory premises. Since the beginning of this year, Yanshan Petrochemical has produced nearly 3,000 tons of aviation gasoline in total, ensuring a stable supply. Over the years, Yanshan Petrochemical has focused on a high-value, differentiated strategy of shifting from conventional oils to specialty products, investing heavily in innovation in the field of aviation fuels and continuously making progress in developing technologies to reduce lead content in aviation gasoline, ultimately achieving lead-free versions of such fuels. From the nationally exclusive Aviation Fuel No. 75 to UL91 lead-free aviation fuel, and from 100LL low-lead aviation fuel to 100VLL ultra-low-lead aviation fuel, the company has developed a comprehensive range of aviation fuel products, positioning itself as a leader in driving the green transformation of aviation fuels in China. As early as 2015, Yanshan Petrochemical took the lead in breaking through technical barriers thanks to two core invention patents: \"A lead-free aviation gasoline (UL91) and its preparation method\" and \"A low-lead aviation gasoline (100LL) and its preparation method\". Among them, UL91 lead-free aviation gasoline has been produced on a large scale in a stable manner, not only filling the gap in domestic production of lead-free aviation gasoline but also making Sinopec the first company in Asia to master the technology for its production, thereby breaking the long-standing technical monopoly held by foreign countries. In recent years, with the opening up of the domestic low-altitude airspace and the rapid development of the general aviation industry, the demand for low-lead and lead-free aviation gasoline has continued to rise. Lianshan Petrochemical, thanks to its comprehensive range of products and reliable supply capabilities, has become an important fuel supplier for general aviation airports and flight schools in China, providing power support for various applications in the low-altitude economy such as aerial tourism, agricultural and forestry spraying, and aeronautical surveying. Against the backdrop of the \"dual carbon\" goals, Yanshan Petrochemical has made extensive efforts in researching and developing UL94 and UL100 aviation fuels. It regards the elimination of lead from aviation fuels as a key approach to achieving green development, aiming to establish a leading production base for clean aviation fuels and thus continuing to contribute to the development of the low-altitude economy.
