In this contribution we explore the combination of hydrogen production via electrolysis with subsequent storage of the hydrogen via catalytic hydrogenation of the LOHC compound dibenzyltoluene (H0-DBT) without hydrogen drying. The objective is to investigate the influence of water on the performance of Pt, Pd, Rh, and Ru (all alumina-supported) catalysts in the hydrogenation of H0-DBT. Our study shows that H0-DBT can be readily and fully hydrogenated even in the presence of a large excess of water, i.e., through the use of a water-saturated LOHC-phase. The hydrogenation activity of the ruthenium catalyst is hardly affected by water, while a slight decrease in hydrogenation activity was found in the presence of water for the applied Rh, Pt, and Pd catalyst. We conclude that wet hydrogen may be utilized in charging the LOHC compound H0-DBT, and thus, energy and drying equipment for producing dry hydrogen can be saved in the production of the hydrogen-rich carrier perhydro dibenzyltoluene (H18-DBT).

用电解产生的湿氢对液态有机氢载体进行充电

在这一贡献中，我们探索了通过电解生产氢与随后通过LOHC化合物二苄基甲苯（H0-DBT）的催化加氢而不进行氢干燥的氢存储相结合的方法。目的是研究水对H0-DBT加氢中Pt，Pd，Rh和Ru（均由氧化铝负载）催化剂的性能的影响。我们的研究表明，即使在大量过量的水存在下，即通过使用水饱和的LOHC相，H0-DBT仍可轻松而完全氢化。钌催化剂的氢化活性几乎不受水的影响，而在水的存在下，所施加的Rh，Pt和Pd催化剂的氢化活性略有下降。我们得出的结论是，湿氢可用于充入LOHC化合物H0-DBT，因此，
