An apparatus and a method for controllably converting aluminum into alane. In the system of the invention, a reaction between aluminum and hydrogen to form alane is performed at temperatures below 100 °C using a supercritical fluid such as CO2 as a reaction medium, with the optional inclusion of a co-solvent, such as an ether, in the reaction vessel. Inert gas is used to exclude unwanted gases such as oxygen. The reaction of aluminum and hydrogen has been observed to proceed at approximately 60 °C using Me2O as an added solvent in CO2 at supercritical pressures.
L'invention concerne un appareil et un procédé servant à convertir de façon contrôlable de l'aluminium en hydrure d'aluminium. Dans l'invention, on effectue une réaction entre de l'aluminium et de l'hydrogène pour former de l'hydrure d'aluminium à des températures inférieures à 100 °C en utilisant un fluide, tel que CO2, en phase supercritique en tant que milieu réactionnel et en incorporant facultativement un co-solvant, tel qu'un éther, dans le réacteur. On utilise un gaz inerte pour exclure des gaz indésirables tels que l'oxygène. Il a été observé que la réaction de l'aluminium et de l'hydrogène a lieu à environ 60 °C si on utilise Me2O en tant que solvant ajouté dans CO2 à des pressions supercritiques.
