Exo-tetrahydrodicyclopentadiene(exo-THDCPD)is a kind of high-energy density hydrocarbon fuel,which can be prepared from dicyclopentadiene by hydrogenation and isomerization reactions.The current research and technical status of exo-THDCPD preparation,including the reaction principle,process route,main technical parameters and so on are summarized.The types and preparation methods of hydrogenation and isomerization catalysts and the research progress of hydrogenation and isomerization processes are introduced.Finally,it is pointed out that the non-noble metal alloy catalysts are the research focus of hydrogenation catalysts.Furthermore,prolonging the life time of supported AlCl3 catalysts,improving the anti-coking performance of zeolite and reducing the production cost of ionic liquid catalysts are three research directions of isomerization catalysts.Increasing the selectivity of the bi-functional catalysts is important for the one-pot preparation of exo-THDCPD.Liquid-phase continuous-flow process is expected to realize the continuous industrial production of exo-THDCPD.
