On September 18, the Jiyuan High-Tech Industrial Development Zone approved the filing of a project for the comprehensive utilization of 250,000 tons of α-olefins per year. Approval number: 2509-419001-04-01-875016. On the evening of August 19, the Jiyuan Demonstration Zone held a meeting to discuss investment promotion projects, emphasizing the need to seize opportunities, strengthen coordination, and facilitate the signing and implementation of such projects as soon as possible. The meeting heard a report on the overall assessment of investment attraction projects, as well as details regarding projects such as the Guangzhou Premium Plant Stem Cell Project, the Anhui Jiahe Generic Drug Manufacturing Base Project, the Angela New Quality Industry-Finance Integration Complex Demonstration Project, Henan Zhongtuolihe’s annual 250,000-ton α-olefin comprehensive utilization project, and the research, application, and demonstration of slope gravity energy storage technology. The meeting discussed in depth key aspects such as the feasibility of these projects, their market prospects, environmental impacts, and the factors necessary for their implementation, conducting a thorough analysis of each project one by one. Henan Zhongtuolihe Chemical Co., Ltd. is located in Luoyang City, known as the \"Imperial Capital for a Thousand Years, the City of Peonies, and the Starting Point of the Silk Road\". The company is engaged in the research, development, production, sales, and market application of coal-based high-purity environmental-friendly alkane products. It has developed its own production facilities for coal-to-oil fine chemicals. Its products fall into four categories: high-purity n-alkanes, isomeric alkanes, environmental-friendly waxes, and phase-change energy storage materials. These products are used in various fields such as food, pharmaceuticals, chemicals, precision instruments, aerospace, and phase-change energy storage, and are sold both domestically and in countries and regions such as South Korea, Japan, India, Vietnam, as well as Europe and the United States. The technology for separating normal and isomeric alkanes from Fischer-Tropsch synthesized oil, independently developed by Henan Zhongtuolihe Chemical Co., Ltd. (referred to as “Zhongtuolihe”), has recently received high recognition from authoritative experts in the industry. According to Zhang Wenshao, chairman of Henan Zhongtuolihe and the person in charge of the technology R&D projects, in early August, the China Association for the Industrialization of Science and Technology organized an expert review meeting at the China Science and Technology Hall in Beijing. Two academicians and more than a dozen renowned experts agreed that the key separation technology developed by Zhongtuolihe for Fischer-Tropsch synthesized oil effectively solves the problems associated with the distillation and purification of n-paraffinic and isoparaffinic hydrocarbon products; it enables efficient separation of these products and thorough removal of impurities, thereby significantly improving their purity and cleanliness. This project fills a gap in the domestic market, addresses the weaknesses in the industry, breaks foreign monopolies, and replaces as well as surpasses imported products; it holds great significance in improving the quality of coal chemical products in China, promoting the transformation and upgrading of the petrochemical industry, and supporting the aerospace sector. During the development of this project, the R&D team overcame various technical challenges, including the development of processes for separating and purifying high-purity alkane products, product dehydration, and the removal of trace amounts of oxidized compounds from the products. A series of pilot-scale tests were carried out, such as hydrodynamic experiments on distillation columns, development of purification processes, selection tests for purification agents, and thermal model tests. In the absence of existing literature and experimental data, the team continued to conduct experiments and adjust parameters in order to optimize the project’s process route, ultimately establishing a viable and efficient production process for the products.
