Safety first. Prevention first: Let’s praise and encourage the achievements made in China’s chemical technology and equipment industry. **********************【Ten Years of Rapid Development in Chemical Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** China National Chemical Corporation’s integrated technology for the green and efficient synthesis of THF from BDO has passed the evaluation for scientific and technological achievements. On July 4th, an evaluation meeting was held by the Research Institute of China National Chemical Corporation regarding this integrated technology for the green and efficient synthesis of 1,4-butanediol (BDO) into furan (THF). The conference was organized by the China Petroleum and Chemical Industry Federation, and well-known experts from industries such as Tsinghua University, Beijing University of Chemical Technology, the China Petroleum and Chemical Industry Federation, Sichuan Tianhua Chemical Group Co., Ltd., and Donghua Engineering Technology Co., Ltd. were invited to assess the scientific and technological achievements of the project. At the review meeting, the project team presented a self-assessment report to the expert panel, detailing the technical development aspects of the project, the results of pilot operations, patents, design documents, and other research achievements. After listening to the presentation by the project team, the expert group carefully reviewed the relevant materials. Through inquiries and discussions, the group unanimously agreed that the project’s catalyst activity, THF selectivity, separation technology, and other parameters all possess significant competitive advantages, and that the project’s achievements are at a leading level in China. The project constructed and successfully operated a 100-ton pilot-scale demonstration unit; it developed new solid acid catalysts as well as an efficient suspended-bed reaction process that enables an increase in THF selectivity while reducing equipment corrosion and emissions. Additionally, distillation was creatively combined with membrane separation technology for the liquid-phase separation of the products, resulting in energy savings of over 30% compared to traditional methods. To address this technology, the Chinese Academy of Chemical Sciences has developed an industrial process package capable of handling 10,000 tons per year; industrial implementation is expected to take place within this year. This move is of great significance for strengthening China’s C4 industry chain by enhancing its capabilities and filling in any gaps, as well as for increasing the proportion of domestically produced core technologies.
