Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On November 24th, the coal-based α-olefin-based technology for producing medium- and low-viscosity mPAO polymers, independently developed by the Research Institute of **Energy Group (Low-Carbon Institute), achieved successful operation on a 10-ton/year continuous-flow reactor, with steady performance throughout. This marks a significant technical breakthrough by **Energy Group in the field of high-quality base oils for lubricants derived from coal chemistry. https://p3-sign.toutiaoimg.com/tos-cn-i-axegupay5k/b313840bbe234247bd6601b91681e089~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1765530986&x-signature=KSMeF6lq1h%2FPYnqWGDMuUNWz5SQ%3D The image shows a solution-phase continuous mPAO polymerization system. In this pilot-scale production process, coal-based α-olefins were used as the main raw material; through precisely controlled polymerization reactions, high-quality mPAO40 and mPAO10 products were successfully manufactured, thereby establishing a production pathway from coal-based α-olefins to high-quality mPAO base oils with medium to low viscosity. The successful pilot-scale application of this technology represented a crucial breakthrough by the Research Institute (Low-Carbon Institute) from scratch in the field of producing medium- and low-viscosity mPAO polymers from coal-based α-olefins. It enabled the development of a core technology framework with full independent intellectual property rights, effectively filling an important gap in China’s supply of high-end lubricant base oils and further improving the structure of China’s coal-based high-end chemicals industry. As a flagship product that distinguishes coal chemical industry products from those based on petroleum, the high-value utilization of coal-based α-olefins is an important direction for promoting the transformation and upgrading of this industry. The Research Institute (Low-Carbon Institute) focuses on the properties of α-olefin resources derived from coal indirect liquefaction, and develops efficient and cost-effective technologies for the separation and purification of high-carbon α-olefins (C8–C12). It has successfully overcome two key technical challenges: the deep deoxygenation of high-carbon hydrocarbons and the separation of alkanes and olefins with low energy consumption. Among them, the \"extraction + chemical\" deep deoxygenation technique is employed to precisely keep the oxygen content in the C₈–C₁₂ high-carbon components below 10 ppm. The independently developed core sequential simulated moving bed adsorption separation technology enables the simultaneous separation of multiple carbon-chain components; the purity of the C8–C12 mono-carbon α-olefins obtained reaches reagent-grade standards. The overall operational cost of this technology is reduced by more than 30% compared to traditional processes, giving it significant economic competitiveness and good prospects for industrial application. https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/230c17b6768dc5877ea11b948ec94659~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1765530986&x-signature=nvtvg4xGuvsvUNz0p89spPr0aKQ%3D The image shows the coal-based high-carbon-number α-olefin products developed by the Academy of Scientific Research (Low-Carbon Research Institute)
