説明

<jats:title>Abstract</jats:title><jats:p>With its low melting point of −17.8 °C and gravimetric density of 5.23 wt %, <jats:italic>N</jats:italic>‐ethylindole is a promising candidate for use as a liquid organic hydrogen carrier (LOHC). Here, the influences of reaction temperature and hydrogen pressure on the hydrogen capacity of <jats:italic>N</jats:italic>‐ethylindole in the liquid phase are studied. It is found that fully hydrogenated <jats:italic>N</jats:italic>‐ethylindole can be achieved at 190 °C within 80 min. The hydrogenation of <jats:italic>N</jats:italic>‐ethylindole over 5 wt % Ru/Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> is found to follow first‐order kinetics with an apparent activation energy of 62.4 kJ mol<jats:sup>−1</jats:sup>; its rate constant is subsequently derived. The initial rate and turn‐over frequency (TOF) at 160 °C–190 °C are also calculated. The structures of the intermediates during hydrogenation of <jats:italic>N</jats:italic>‐ethylindole are discussed based on the results of density functional theory calculations. Finally, the hydrogenation mechanism for <jats:italic>N</jats:italic>‐ethylindole is established.</jats:p>
