Competitive effects of compounding aromatic hydrogen storage carriers in low-pressure hydrogenation reactions
Year: 2024
Type: article
Abstract: The reactivity of various liquid organic hydrogen carriers (LOHCs) over 5 wt% Rh/C and 5 wt% Ru/C catalysts is evaluated. The results show that monocyclic aromatic hydrocarbons have the highest reactivity, followed by monocyclic aromatic rings, while polycyclic and fused cyclic aromatic hydrocarbons have relatively low activity. It is also found that mixing different LOHCs leads to a competitive effect, resulting in lower reactivities for all LOHCs. As the degree of LOHC hydrogenation increases, the adsorption of multi-step hydrogenation intermediates becomes more difficult, resulting in lower yields of fully hydrogenated products. It is important to understand the behavior of LOHCs in hydrogenation reactions and to optimize the performance of LOHCs compound systems.
