On November 27, an announcement was issued regarding the result of the single-source procurement process for the preparation of the preliminary design for the 2025 pilot-scale process verification and optimization project related to coal-based polyolefin elastomers at Ningxia Coal Industry’s Olefins Branch No. 1. Supplier selected: Sinopec Ningbo Engineering Co., Ltd. Announcement period: from November 27, 2025, to November 30, 2025. Purchaser: **Energy Group Ningxia Coal Industry Co., Ltd. On August 21, 2024, the list of candidates shortlisted for the public bidding project related to the development and preparation of the process package for a 1,000-ton/year POE pilot plant was made public by the Ningxia Coal Industry Coal Chemistry Industry Technology Research Institute. First winning bidder: Sinopec Ningbo Engineering Co., Ltd. This project is part of the **energy technology innovation project titled ‘Development of a Complete Process Technology for Polyolefin Elastomers (POE)’, and it primarily involves the development and preparation of the process package for a 1,000-ton/year POE pilot plant. The project converts the heavy olefins, which are by-products of coal-to-oil production, into high-value POE products, thereby significantly improving the overall efficiency of utilizing coal as a raw material in the chemical industry. It changes the pattern of the coal chemical industry, which is currently focused on basic products, and opens up a high-value industrial chain pathway of \"coal-α-olefins-high-end elastomers\" for this sector. During 2024–2025, Ningxia Coal Industry applied for two key patents: one is a device and method for removing volatile components from polyolefin elastomer polymers, which helps to prevent polymer clogging in the distillation process ； The second is the solution polymerization production system for polyolefin elastomers, which addresses issues such as delayed temperature control during the polymerization reaction, as well as risks related to excessive temperature and pressure. In addition, development of dedicated polymerization reactors with a capacity of thousands of tons has been carried out; by establishing multi-scale coupled models, the reaction process is accurately simulated to optimize reactor design. In 2022, the pilot-scale separation project for the production of α-olefins from FTO oil products by Ningxia Coal Industry completed the entire process, successfully producing C6 and C8 alkenes with a purity of over 99%. On July 11, 2025, **Energy Group Ningxia Coal Industry Co., Ltd. published a public notice regarding the environmental impact assessment for the project aimed at optimizing α-olefin separation technology and scaling up its implementation. Construct a facility capable of producing 796 tons per year of 1-hexene and 476 tons per year of 1-octene, with an annual by-product of 1,411.52 tons of a C6/C8 alkane mixture.
