The key technology development for the production of α-olefins from Fischer-Tropsch oil and the pilot-scale demonstration project have passed acceptance! On March 20, 2025, the Science and Technology Department of the Energy Group organized a meeting in Ningdong to conduct the acceptance review for the scientific and technological innovation project titled “Development of Key Technologies for the Production of α-Olefins from FTO Oil Products and Pilot-Scale Demonstration”. The expert group listened to reports on the project implementation, reviewed the technical documents and related materials. After on-site inspections and discussions, the group concluded that all the research tasks specified in the project scope had been completed and that all the required assessment criteria had been met, and therefore approved the project for acceptance. Through research on key technologies such as the washing of naphtha using Fischer-Tropsch synthesized oil, and the deacidification, deoxygenation, and separation of heavy oils, this project developed key technologies and processes for the separation and purification of C6, C8, and other compounds ； Through research on new processes for producing α-olefins from FTO synthesis oil naphtha using \"extractive distillation + distillation\", \"etherification reaction + distillation\", and \"molecular sieve adsorption deoxygenation\", a process technology for the separation and purification of polymeric-grade 1-hexene, 1-heptene, and 1-octene from FTO-based products was developed. The stable heavy oil separation technology was verified using a 5 kg/h pilot plant. A pilot plant was built and operated, and third-party testing of the products after 72 hours of performance evaluation showed that they met the design requirements. Through the implementation of this project, key technical support has been provided for future breakthroughs in the separation technology of FTO-grade α-olefins ； Accelerate the progress of the pilot project for the high-purity separation of kiloton-scale α-olefins, in order to break the reliance on imports for α-olefins with a carbon chain length of C7 and above ； Provide raw material support for high-end α-olefin-derived products such as high-carbon alcohols, POE, and PAO, thereby facilitating the rapid development of the high-end materials and fine chemical industries
