Latest Patents
One of Brent S DeFeo's latest patents is a system and method for the disposal of hydrazine propellants. This invention describes an apparatus and method for converting hydrazine, substituted hydrazines, and other nitrogen-containing explosive materials, particularly unsymmetric dimethyl hydrazine (UDMH), into ammonia or ammonia and corresponding amines through hydrogenation. The process involves diluting hydrazines with a suitable carrier fluid, preferably water, mixing with hydrogen, and hydrogenating in a catalyst reactor. The commercially valuable ammonia and amines are then separated, while the separated carrier fluid and hydrogen gas can be recycled to conserve energy and reduce waste. Additionally, the apparatus is designed for disassembly and transport to hydrazine disposal sites.
Another significant patent by DeFeo focuses on a method for converting hydrazine and substituted hydrazines into ammonia or amines through hydrogenation over a supported Group VIII metal catalyst. This method allows for the hydrazines to be dissolved in a suitable solvent and hydrogenated at temperatures ranging from 0 to 250 degrees Celsius, followed by the separation of valuable ammonia and amines. Alternatively, a gas phase reaction may be employed.
