Decomposition of Hydrazine on Shell 405 Catalyst at High Presure

Abstract: The decomposition of hydrazine on Shell 405 catalyst has been studied at pressures from 500 to 5050 psi. A novel laboratory apparatus was developed with which the propellant flow rate and reaction pressure could be remotely and independently varied and monitored. Virtually unlimited run times were possible.

“…[1,2] Potential and established uses range from protective coatings [3] and spintronic devices [2] to catalyst and electrode materials for a wide variety of reactions including methanol oxidation, [4] water splitting [5][6][7][8][9][10] and hydrazine decomposition, e. g. in monopropellant rocket engines. [11,12] Ir nanoparticles (NPs) and thin-films are of particular interest for these catalytic applications since their increased surface-to-volume ratio allows for a more efficient noble metal utilization. [7] While dispersed Ir NPs are often prepared by wet-chemical methods, [13][14][15][16] Ir thin films can be deposited by various techniques including electroplating, [9,[17][18][19] pulsed laser deposition, [20,21] chemical vapor deposition [22] and atomic layer deposition (ALD).…”

“…100 nm), stuck together by an amorphous alumina binder. The ammonia selectivity increases with increasing pressure and decreasing bed length, but remains independent of the bed loading [87,88]. Ir crystals display an average size of around 2 nm (190 m 2 g −1 -Ir for the fresh catalyst) and show an epitaxial growth on the support with (110) orientation, which increases with firing time [36,86].…”

“…. Moreover, heterogeneous catalysis of hydrazine with Ir and other transition metals have shown to yield spontaneous ignition [ignition delay times (IDT) of ∼10–100 ms] near room temperature with simple engineering design constraints. However, inhaled, oral, or dermal exposure to hydrazine is extremely dangerous, thus requiring significant costs in manufacturing and handling . Hence, the use of energetic ILs (EILs) with much higher heats of combustion offers a variety of green monopropellants that are less toxic, easier to store, and overall more environmentally friendly materials suited for in-space propulsion applications …”
