摘要
液体有机氢载体(LOHC)储氢技术是一种安全、经济的储氢方式,其规模化应用对我国能源转型和能源安全具有重要意义,但LOHC脱氢是强吸热的液固反应析氢过程,如何设计高效的脱氢反应器改善传热传质,已经成为严重制约LOHC发展的关键问题之一。通过总结不同类型的脱氢反应器,分析了其技术现状;比较了悬浮式、固定床式和壁式催化剂的反应器、膜反应器的优缺点和适用条件;最后对脱氢反应器的现有问题和未来发展进行讨论,可为下一步研究提供参考。
Hydrogen storage technology using liquid organic hydrogen carrier(LOHC) is a safe and economical way to achieve hydrogen storage and transportation,and its large-scale utilization is of great significance to promote the clean and efficient use of fossil energy and ensure energy security.However,the dehydrogenation of LOHC is a process where the large amounts of heat is needed and a huge volume of gas is produced by chemical reaction between liquid and solid.How to design an efficient dehydrogenation reactor to optimize heat and mass transfer has become one of the key issues that seriously restrict the development of LOHC.Therefore,different types of dehydrogenation reactors are summarized and the current development of the technology is analyzed.In addition,the advantages/disadvantages and the applicable conditions of suspended,fixed,and monolithic catalysts,membrane reactors are compared.At last,the existing problems of the dehydrogenation reactor are discussed and an outlook on the future development for the next research has been prospected.
