Yongrong Technology Solves the Challenge of Efficient Utilization of Cyclohexane According to Sinochem News, recently Fujian Yongrong Technology Co., Ltd. succeeded in finding a way to integrate cyclohexane dehydrogenation technology with hydrogen storage and transportation. This has enabled the 180,000-ton-per-year cyclohexane-based production facility to increase its output capacity, offering what could be considered a safe and economical \"Yongrong solution\" for the large-scale use of hydrogen energy. The cyclohexane dehydrogenation technology was developed over many years through joint efforts by Yongrong Technology, Yanchang Beijing Petroleum Design Institute, and catalyst manufacturers. This technology converts cyclohexane, a by-product of the olefin process **units, into benzene and hydrogen, which are then directly reused in the benzene hydrogenation step of **production or in the production of hydrogen peroxide. By utilizing this technology, Yongrong Technology built and put into operation a **cyclohexane coupling unit in 2019, raising the carbon atom utilization rate from 75% to 98% and overcoming the challenges associated with the recycling of cyclohexane resources. In May 2021, this technology was rated as \"world-first and industry-leading\" in an assessment organized by the China Petroleum and Chemical Industry Federation. Subsequently, Yongrong Technology developed an organic liquid hydride hydrogen storage technology that uses the hydrogenation of pure benzene to produce liquid cyclohexane with stable properties (i.e., hydrogen oil). The hydrogen storage density reaches 55–60 grams per liter, and the amount of hydrogen that can be stored is three times that of traditional high-pressure hydrogen storage methods; as a result, transportation costs are reduced by 70%. Hydrogen oil can make use of existing petroleum storage and transportation facilities; it only requires low-cost modifications to be integrated into the hydrogen energy network, and it can be stored and transported safely at normal temperature and pressure. Furthermore, catalytic dehydrogenation of the hydrocarbon oil can produce hydrogen with a purity of 99.99%, meeting the requirements of fuel cells; the benzene obtained after dehydrogenation can be recycled for hydrogenation, resulting in an overall energy efficiency of 98%. This technology is expected to overcome the bottlenecks in the cross-regional transportation of green hydrogen, thereby accelerating the commercialization of hydrogen energy. On this basis, Yongrong Technology combines cyclohexane dehydration with hydrogen storage technology to create a synergistic effect of \"resource recycling + energy upgrading\"; in other words, cyclohexane serves both as a high-value-added raw material and as a hydrogen storage medium that contributes to the development of the hydrogen energy industry. This closed-loop model is expected to enable a single **project to reduce carbon dioxide emissions by over 100,000 tons per year, while also cutting costs in the hydrogen industry chain by more than 30%.
