AI Technical Summary
Technical Problem
Existing methods for handling dihydrogen using liquid organic hydrogen carriers involve hazardous and toxic compounds, expensive catalysts, and high energy costs, diminishing their economic viability.
Method used
A method involving a lactone as the first organic compound and a terminal diol as the second organic compound, utilizing Cu-based catalysts and adiabatic conditions for hydrogenation and dehydrogenation reactions, with the dehydrogenation step occurring in a gaseous phase where the lactone condenses, offsetting the endothermic reaction by heat generated from condensation.
Benefits of technology
This approach reduces energy consumption, maintains reaction efficiency, and uses safer, less toxic compounds, facilitating cost-effective dihydrogen handling and storage.
