Recently, the **Pilot-scale Process Verification and Optimization Project for Coal-based Polyolefin Elastomers by Ningxia Coal Industry Co., Ltd., a subsidiary of the Energy Group, was approved for registration. According to reports from January, **Ningxia Coal Industry Company, part of the Energy Group, successfully completed the entire process for its 10,000-ton capacity α-olefin separation unit during a single trial run. The unit produced 1-hexene of polymer-grade purity exceeding 99% and 1-octene of purity over 98%. This achievement marks a significant breakthrough in China’s field of separating high-value chemical raw materials derived from coal, it extends the industrial chain related to α-olefins obtained through coal indirect liquefaction, and it lays a solid foundation for the development of downstream industries such as polyolefin elastomers and metallocene polyα-olefins. The project was launched in 2019. After 6 years of effort, the R&D team developed an \"extraction distillation/catalytic distillation\" separation process, overcoming technical challenges such as the deep deoxygenation of Fischer-Tropsch oil, the separation of alkanes and alkenes with the same carbon count, and the purification of high-purity α-alkenes. They moved from single-point experiments to the integration of the entire process technology, thereby creating a set of α-alkene separation processes with independent intellectual property rights. It is reported that the device has passed the 72-hour performance test organized by the China Petroleum and Chemical Industry Federation. The separation process route for α-olefins features a reasonable flow, a feasible scheme, and reliable technology. The successful commissioning of this facility provides the core technical support for the industrial production of 1-hexene and 1-octene on a 100,000-ton scale via FTO process.
