Processes are provided for the storage and release of hydrogen by means of dehydrogenation of hydrogen carrier compositions where at least part of the heat of dehydrogenation is provided by a hydrogen-reversible selective oxidation of the carrier. Autothermal generation of hydrogen is achieved wherein sufficient heat is provided to sustain the at least partial endothermic dehydrogenation of the carrier at reaction temperature. The at least partially dehydrogenated and at least partially selectively oxidized liquid carrier is regenerated in a catalytic hydrogenation process where apart from an incidental employment of process heat, gaseous hydrogen is the primary source of reversibly contained hydrogen and the necessary reaction energy.
提供了通过氢载体组分的脱氢作用来储存和释放
氢气的过程,其中脱氢的部分热量由载体的氢可逆选择性氧化提供。实现了自热产氢,其中提供足够的热量以在反应温度下维持至少部分的内源性脱氢反应。至少部分脱氢和至少部分选择性氧化的液体载体在催化加氢过程中再生,在此过程中,除了偶然使用的过程热量外,气态氢是可逆地包含氢和必要反应能量的主要来源。
