摘要:
In one aspect, the invention provides a hydrogen storage material that is formed by reacting solid precursors (a) and (b). The (a) precursor is a compound containing X-H and Y-H bonds, where X is a Group 13 and Y is a Group 15 element. Preferably X is boron (B-H) and Y is nitrogen (N-H). Most preferably, the precursor (a) is borazane. The (b) precursor is preferably a hydride, such as LiH or LiAIH 4 . Another feature of the present invention is a novel hydrogen storage composition material that is formed as an intermediate (INT) in the reaction of the (a) with the (b) precursors. The INT hydrogen storage material can be a quaternary B-H-Li-N composition. Other aspects of hydrogen storage materials are provided herein.

A gas supply and containment assembly (100) includes a gas cabinet (102) defining an interior volume (104) and including cabinet flow circuitry (106) coupleable to a high pressure gas cylinder (108) positionable in the gas cabinet (100), for flowing a hazardous constituent gas from the cylinder (108) through the flow circuitry (106) for discharge to end use facilities. An outer enclosure (110) contains the gas cabinet (102); a scrubber unit (112) including a sorbent material which is sorptively selective for the hazardous gas constituent; an enclosure flow circuitry (114) which is coupleable to a source of inert gas. Low level leakages are withdrawn in the inert gas flowed at a low rate into the gas cabinet (102) and scrubbed in the scrubber (112) in the outer enclosure (110).

摘要:
In one aspect, the invention provides a method of storing hydrogen that comprises reacting two precursors to form a hydrogen storage composition comprising hydrogen, nitrogen, a Group 13 element, and an element selected from Group 1, Group 2 or mixtures thereof. In other aspects, the present invention provides a method of storing hydrogen by ball-milling two precursors at a temperature in a range sufficient to prevent pre-mature release of hydrogen, while the temperature is still sufficient to induce reaction between the precursors. The precursors preferably have X-H, Y-H and A-H bonds where X represents a Group 13 element, Y represents a Group 15 element, and A represents an element from Group 1, Group 2, or mixtures thereof. Other variations of the methods of storing hydrogen are further provided.
