Competitive effects of compounding aromatic hydrogen storage carriers in low-pressure hydrogenation reactions
The reaction activity of various liquid organic hydrogen carriers (LOHCs) over 5 wt% Rh/C (BET surface area 933.5 g/cm3, pore size 4.6 nm, metal dispersion 10.5 %) and 5 wt% Ru/C (BET surface area 888.4 g/cm3, pore size 6.1 nm, metal dispersion 8.9 %) 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.
期刊介绍:
Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
