摘要:

在全球能源转型与可持续发展的背景下,液态有机储氢(LOHCs)技术作为氢能安全高效储运的重要方案,已成为氢能产业的研究热点。环烷烃储氢载体,如甲基环己烷和环己烷,因其较高的储氢密度、低廉的价格和良好的化学稳定性,成为LOHCs的重要选项。然而,环烷烃的脱氢反应效率和选择性受到多种因素的制约,必须深入研究反应器的设计策略,优化催化剂与反应器之间的匹配。本文系统论述了各类反应器基于传质和传热特性提升的设计策略,详细阐述了其对催化环烷烃脱氢高效释放氢气性能优化的重要影响。深入分析了环烷烃脱氢反应器内传质、传热、传动与反应过程之间的协同作用并加以利用,不仅能够大幅提高环烷烃脱氢效率,还能显著提升能量与资源的利用率。结合前沿的反应器设计理念、多尺度建模与实验验证,有望为高性能脱氢反应器的开发与优化及其在工业中的应用提供重要的理论基础和技术路径,为化工过程的效率提升和可持续发展提供新的指引。

Abstract:

Against the backdrop of global energy transition and sustainable development, the technology of liquid organic hydrogen carriers (LOHCs) is emerging as a pivotal solution for the safe and efficient storage and transportation of hydrogen, gradually capturing the attention of the hydrogen energy sector. Cycloalkanes, such as methylcyclohexane and cyclohexane, have become significant choices for LOHCs due to their high hydrogen storage density and excellent chemical stability. However, the efficiency and selectivity of the dehydrogenation reactions of cycloalkanes are constrained by various factors, necessitating an in-depth exploration of reactor design strategies to ensure a profound synergy between the catalyst and the reactor. This paper systematically discusses the design strategies for enhancing the mass and heat transfer characteristics across various reactor types, and elucidates their critical impact on optimizing the catalytic performance for the efficient release of hydrogen from cycloalkanes. Through a comprehensive analysis of the synergistic interactions among mass transfer, heat transfer, momentum transfer, and reaction processes within cycloalkane dehydrogenation reactors, this study demonstrates that optimized reactor designs could not only significantly enhance dehydrogenation efficiency but also markedly improve the utilization of energy and resources. By integrating advanced reactor design concepts, multiscale modeling, and experimental validation, this research provides a vital theoretical foundation and technical pathway for the development and optimization of high-performance dehydrogenation reactors and their industrial applications, thus offering new directions for enhancing the efficiency of chemical processes and promoting sustainable development.
