Abstract

Abstract:

Hydrogen energy is an important support for achieving the dual-carbon goal, and the technology based on liquid organic hydrogen carriers (LOHCs) is significant for developing hydrogen energy. Aromatic heterocyclic compounds as hydrogen storage carriers have attracted research interests from the field of research and industry. But, there is no enough and in-depth research efforts on low efficiency during the hydrogenation process. To complete the scientific design and process optimization of hydrogenation, the research on solubility and phase equilibrium concerning the hydrogen storage system is indispensable. The LOHCs hydrogenation involves a sequential process composed of physical dissolution and chemical reaction in the gas-liquid-solid three-phase system. The hydrogen for hydrogenation comes from the hydrogen dissolved in the liquid. However, due to the lack of fundamental data concerning solubility and phase equilibrium of hydrogen in the liquid phase, the current kinetic calculations for hydrogenation are not accurate and require correction of the solubilities of hydrogen in different LOHCs. This article describes the current research status regarding hydrogen solubility in LOHCs, involving the solubilities of pure hydrogen and some mixed gases in LOHCs. The types, advantages and disadvantages of the experimental methods used for hydrogen solubility are described in details. Experimental devices are built based on different experimental methods, and the correlation model and prediction model of the determined data are briefly discussed.

Key words: solubility, phase equilibrium, liquid organic hydrogen carriers (LOHCs), hydrogen, hydrogenation

摘要：

氢能是实现“双碳”目标的重要支撑，而有机液态储氢载体（liquid organic hydrogen carriers，LOHCs）技术是发展氢能的重要研究内容，芳杂环储氢载体是目前研究的热点。迄今为止，国内外对加氢过程效率低的问题尚缺乏深入的研究，为了完成加氢过程的科学设计与优化，储氢体系相关的溶解行为与相平衡研究不可或缺。LOHCs加氢反应涉及气液固三相体系的物理溶解-化学反应串联过程，加氢所需氢气来自液体中溶解的氢，而由于氢气在液相中的溶解度与相平衡数据的缺失，现有的LOHCs加氢反应动力学计算并不准确，这需要氢气在不同LOHCs中的溶解度数据修正。本文对氢气在有机液体中溶解度的研究现状进行了阐述，涉及单一氢气的溶解度和混合气体在有机液体中的溶解度。本文详细描述了研究氢气溶解度时所采用的实验方法的种类及优缺点，依据实验方法的不同搭建了实验装置，对数据的关联模型及预测模型进行了讨论。
