The \"Acetylene Hydrogenation Process and Equipment for Ethylene Production\", developed jointly by the Research Institute of Shenwu Technology Group and Beijing Huafu Engineering Company, has passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. Industry experts say that the “acetylene hydrogenation to ethylene technology” is a breakthrough in the field of modern coal chemical processing, and it holds the potential to reduce China’s reliance on imported ethylene. It is understood that through on-site inquiries and discussions, as well as the review of project development reports and third-party testing and evaluation reports, the appraisal committee concluded that Shenwu’s \"acetylene hydrogenation process and equipment for producing ethylene\" fills a gap in the technology for producing ethylene from high-concentration acetylene both domestically and internationally, and exhibits significant innovation. The appraisal committee is composed of 9 renowned domestic and international chemical engineering experts from institutions such as Tsinghua University, the Research Institute of Petrochemical Science, the Petrochemical Planning Institute, Tianchen Company, Shenhua Research Institute, China University of Mining and Technology, and Shanxi Lu’an Group. Academician Jin Yong and Academician Shu Xingtian of the Chinese Academy of Engineering serve as the chairman and vice-chairman of the appraisal committee, respectively. The pilot plant built using the \"acetylene hydrogenation to ethylene technology and equipment\" demonstrated, through 72 hours of full-load operation on-site, an acetylene conversion rate of 98.90% and an ethylene selectivity of 91.06%. To date, 58 patents at home and abroad have been applied for for this achievement, with 32 patents already granted. The evaluation committee unanimously agreed that this technology and equipment are of great significance for widespread adoption, and recommended accelerating the construction of large-scale industrial demonstration facilities. Shenwu Technology Group is primarily engaged in the development, transformation, and market promotion of technologies for the efficient and clean utilization of coal. Given China’s abundant coal resources and the huge demand for raw materials in the chemical industry, Shenwu Technology Group has independently developed a \"new regenerative calcium carbide production process\" and achieved continuous and stable operation of industrial demonstration units, thereby expanding the pathways and possibilities for the deeper processing of acetylene-based products. On this basis, through the in-depth development of the \"acetylene hydrogenation to ethylene technology,\" a technical system for coal chemical processing using the acetylene method unique to Shenwu was established. Compared with traditional coal chemical processes based on gasification, this technical approach offers advantages such as lower investment requirements, higher energy conversion efficiency, reduced water consumption, lower CO2 emissions, and lower production costs for products. It represents a new breakthrough in China’s technology for the differentiated and graded utilization of coal, and several industrial demonstration projects are currently under construction. Experts believe that once this technology is widely adopted, it will help reduce China’s reliance on imported ethylene, thereby alleviating the pressure on the industry involved in producing olefins through naphtha cracking. This holds strategic significance for ensuring the healthy development of China’s economy and safeguarding its energy security. Jin Yong, director of the appraisal committee and an academician of the Chinese Academy of Engineering, said: “This technological achievement makes large-scale hydrogenation of acetylene to produce ethylene possible, bringing new opportunities for the healthy and sustainable development of ethylene and its downstream industries in our country. It is of great significance for promoting the development of coal chemical industry in China and for establishing diversified production routes for ethylene raw materials.”
