Abstract

Abstract:

As an important secondary energy, hydrogen is of high energy density, environmental friendliness and wide use, which is an important direction of human strategic energy development. However, hydrogen storage and transportation are still facing problems of high cost and safety. The hydrogen storage and release technology based on liquid organic hydrogen carriers (LOHCs) has become one of the available technologies with its advantages of relatively high hydrogen storage density, mild storage conditions and convenient transportation. Compared with polycyclic aromatic hydrocarbons, nitrogen-containing LOHCs is milder in catalytic hydrogenation and dehydrogenation, which can effectively improve the robustness of hydrogen storage and release and the reaction efficiency. Based on this, this paper systematically reviewed the progress in hydrogenation and dehydrogenation of nitrogen-containing LOHCs, and revealed the reaction pathway and catalytic mechanism of these two kinds of reactions. Then, the hydrogenation/ dehydrogenation catalysts were systematically summarized from the aspects of active center, support, bimetallic synergistic effect, reaction conditions, catalyst stability, etc. After that, the reaction kinetics models based on the series reactions and reaction network were analyzed in detail. At last, the current challenges of nitrogen-containing LOHCs were introduced, as well as the perspectives of LOHCs systems. However, there are still many problems for this technology, and further in-depth research should be conducted in the aspects of formulation system of organic hydrogen carriers, continuous hydrogen storage and release reaction system, catalyst design and preparation, structure-activity relationship of catalysts, precise reaction kinetics, and comprehensive physicochemical properties database.

Key words: hydrogen, nitrogen-containing LOHCs, reaction mechanism, catalyst, reaction kinetics

摘要：

氢能源作为重要的二次能源，能量密度大、环境友好且用途广泛，是人类战略能源发展的重要方向。然而，氢气储运仍面临较大的成本和安全难题，有机液体储氢化合物（LOHCs）储放氢技术以其储氢密度较高、储存条件温和、运输方便等优势成为氢气储运可供选择的技术之一。相比稠环芳烃类化合物，含氮有机储氢化合物具有更温和的催化加氢和脱氢条件，可有效提高储放氢鲁棒性和反应能效。基于此，本文系统综述了含氮有机储氢化合物加氢及脱氢反应研究进展，阐述了两类反应的路径和催化作用机制，从催化剂活性中心和载体、双金属协同效应、反应条件、催化剂稳定性等方面系统分析了加氢/脱氢催化剂，并详细总结了基于连串反应、反应网络等模型的反应动力学。介绍了含氮有机储氢化合物储氢技术目前面临的挑战并提出未来的研究思路及展望。但是该技术仍存在较多问题，应在有机储氢化合物配方体系、储放氢连续反应系统、催化剂设计与制备、催化剂构效关系、精准反应动力学和全面理化性质数据库等方面进行深入研究。
