摘要：
Hydrogen produced using renewable energy，i.e.，green hydrogen，can achieve zero carbon emission and is one of the ways to promote green energy transition and realize carbon neutrality. Hydrogen storage and transportation technology imposes great difficulties on the large-scale application of green hydrogen. Liquid organic hydrogen carriers(LOHCs)，which mainly include cycloalkanes/aromatics，have become a key technology for long-distance hydrogen delivery because of their high hydrogen storage density，safety and efficiency，and convenient transportation. Compared with the mature aromatic hydrogenation technology，the development of hydrogen-rich LOHC(cycloalkanes)dehydrogenation technology is more difficult and has been a hot research topic in recent years. This paper systematically reviews the research progress in the dehydrogenation technologies of four typical types of cycloalkanes：cyclohexane(CH)，methylcyclohexane(MCH)，decahydronaphthalene(DHN)，and fully hydrogenated dibenzyltoluene (H18-DBT). Herein ， the dehydrogenation reaction pathways and mechanisms of monocyclic(CH and MCH)and polycyclic alkanes(DHN and H18-DBT)are described based on the current research results. Furthermore，this paper summarizes the design ideas，structure-performance relations，and research progress in dehydrogenation catalysts with a focus on active components and carriers，analyzes the dehydrogenation kinetics of hydrogen-rich LOHCs in detail based on different models，and discusses the advantages and disadvantages of four types of typical dehydrogenation reaction devices. In general，the industrial application of cycloalkanes as LOHCs remains a long way off. Continuous improvements in the dehydrogenation kinetics and dehydrogenation mechanisms，enhancements in the catalytic activity and stability of Pt catalysts，development of nonprecious metal catalysts with practical applications，and optimization of the reactor structure have become the key points of the future research on cycloalkanes dehydrogenation technology. © 2024 Tianjin University.
