萘-十氢萘有机液体储氢技术研究进展OA北大核心CSTPCD

The inefficient storage hydrogen is the bottleneck that restricts the large-scale application of green hydrogen energy.Compared with the existing hydrogen storage technologies,naphthalene-decalin organic liquid hydrogen storage,as a highly promising hydrogen storage technology,is expected to provide a new and efficient solution for future energy storage and utilization.The naphthalene-decalin hydrogen storage system can enhance the hydrogen storage capacity of organic liquids,improve the hydrogenation/dehydrogenation cycle and increase economic efficiency.The research progress on naphthalene-decalin organic liquid hydrogen storage technology was reviewed,and the mechanisms of naphthalene hydrogenation and decalin dehydrogenation were analyzed,and the structures of catalysts,processes and technical economy of naphthalene hydrogenation and decalin dehydrogenation were discussed,and the main challenges of naphthalene-decalin organic liquid hydrogen storage technology were summarized.Starting from the key points of demand,through in-depth exploration of the mechanism of decalin dehydrogenation,highly efficient catalysts from the atomic point of view are designed and structures of catalyst surface are constructed to improve the efficiency of decalin dehydrogenation and promote the commercialization of naphthalene-decalin organic liquid hydrogen storage technology.
