Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Continuous updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On July 3, the mixed aromatic hydrocarbon conversion catalyst project, developed jointly by the Research Institute of Liaoyang Petrochemical Company and Tongji University, completed full-scale industrial testing. The test results show that key performance indicators such as catalyst activity and selectivity meet the design requirements. Lu Jie, head of the Aromatic Hydrocarbons Research Laboratory at the R&D Institute of Liaoyang Petrochemical Company, explained that since 2020, he has adopted as a core strategy the development of a \"differentiated technical framework for the flexible conversion of the entire carbon chain of aromatic hydrocarbons\" with independent intellectual property rights, aiming to overcome the limitations of traditional processes. By carrying out precise and targeted conversions and optimal arrangements of components such as p-xylene, aromatic hydrocarbons, and heavy aromatic hydrocarbons, it is possible to expand the range of raw material sources and achieve dynamic and flexible adjustments to the product structure, thereby adapting to market fluctuations and evolving demands. The successful development and industrial validation of this catalyst for the efficient conversion of mixed aromatics mark the complete industrial validation of the technology for the conversion of the entire carbon chain in aromatics. The successful development of key technologies for the conversion of mixed aromatics not only provides a new approach for processing the bottom oil from the deheptanization tower at this company, but also offers alternative catalysts for traditional catalytic production. These technologies will be promoted and applied in CNPC’s and other domestic aromatics plants. Currently, China’s consumption of xylene is on the rise, and it is expected to reach a peak level of around 52 million tons by 2035. This will lead to a fundamental change in the market supply-and-demand dynamics. Traditional aromatic compound production facilities, which are designed to maximize output, face the risk of overcapacity, while the existing technologies for aromatic compound production have limitations in terms of raw material adaptability and product structure flexibility. In the face of this severe challenge, Liaoyang Petrochemical has taken proactive steps since 2020, adopting as its core strategy the development of a \"differentiated aromatic hydrocarbon full-carbon chain flexible conversion technology system\" with independent intellectual property rights. By precisely directing and optimizing the conversion of components such as p-xylene, aromatics, and heavy aromatics, the company has managed to significantly expand the range of available raw materials and enable dynamic, flexible adjustments to its product structure, thus effectively addressing market fluctuations and evolving demand. The successful development and industrial verification of this catalyst for the efficient conversion of mixed aromatics represent the final achievement following the development of catalysts for efficient benzene production and catalysts for the conversion of polycyclic aromatics. It constitutes a key milestone in the implementation of the strategy for the flexible conversion of the entire carbon chain in aromatics, signaling that the technology for converting the entire carbon chain in aromatics has fully undergone industrial verification. The successful development of key technologies for mixed aromatic conversion not only provides a new approach for the company to process deheptanized bottom oil, but also offers alternative catalysts for traditional disproportionation processes. It has the potential to replace the catalysts developed by UOP and the Shanghai Research Institute, and to be applied in petroleum companies and domestic aromatic compounds production facilities in China. In the future, with the successful development of advanced technologies for benzene production, aromatic mixture conversion, and polycyclic aromatic hydrocarbon conversion, these technologies will play a significant role in improving the quality and efficiency of the aromatic hydrocarbons industry as well as driving revolutionary advancements in China’s petroleum aromatic hydrocarbons production techniques. They will serve as innovative models that can be used to facilitate technological upgrades within the industry.
[2024-12-18] Amidst the increasingly fierce competition in the chemical industry, Liaoyang Petrochemical insists on using technological innovation as the primary driver for its development. It continues to explore new paths for transformation and upgrading, and works to build a integrated framework that combines the industrial chain with the innovation chain. The company’s efforts to strengthen itself through technology and innovation are gaining momentum. On December 16th, in the Aromatic Hydrocarbons Research Laboratory of Liaoyang Petrochemical’s Research Institute, researchers were working on industrial-scale tests related to key catalysts for the conversion of mixed aromatic hydrocarbons, aiming to develop new techniques for aromatic hydrocarbon production that reflect Liaoyang Petrochemical’s unique characteristics. This is a microcosm of Liaoyang Petrochemical’s role in driving the engine of technological innovation. Since the beginning of this year, Liaoyang Petrochemical has made technological innovation the primary driving force for its development. It has improved its technological governance system, using the company’s key technological projects as a foundation and major on-site experiments as a means to develop a clear plan of action. The company is moving forward steadily toward building itself on a foundation of technology and strengthening itself through innovation. Led by technology, the innovation chain is developed in line with the industrial chain. Liaoyang Petrochemical has made thorough reforms to its technological systems and mechanisms, making full use of the \"5+5+5\" joint innovation platforms and the 4 joint innovation centers. By aligning the innovation chain with the industrial chain, it has improved the \"product manager + customer manager + process manager\" model, defined clear priorities for technological innovation, and increased support for the transformation and application of \"high-precision, advanced\" technologies. Externally, it forms partnerships with research institutions and leading enterprises to collaborate on innovation; internally, it fosters coordination among chief technical experts and various professional management teams. This creates a comprehensive research framework under the leadership of the party committee, with departments taking the lead, full participation from all staff, and efforts focused across the entire value chain, thereby promoting deeper development in technological innovation. By adhering to targeted measures that address the key challenges and bottlenecks in innovation, Liaoyang Petrochemical focuses on its weaknesses and limitations, expanding the scope and depth of its technical research efforts. It encourages the use of new technologies for the first time, promotes optimization of production processes and improvement in quality, resulting in a continuous stream of innovative achievements. For the first time, ecological polyester sheets and specialty copolyester materials for medical packaging were produced, successfully expanding the market for mid-to-high-end products ； Industrial tests were conducted on lithium battery separator materials, and the LH064 grade product was identified by the refining and chemical sector as a key product for substitution of imported materials under the \"task assignment and leadership\" initiative ； The focus areas for quality improvement have been identified; the impact strength of the high-melting-point copolymer LEP548R polypropylene product has increased by 7.8%, and its quality has been recognized by users.
