High-Temperature Decomposition and Thermal Explosion of Liquid Propellant Components: Hydrogen Peroxide and Hydrazine

Selective decomposition of hydrazine over metal free carbonaceous materials

“…26,31 In order to generate hydrogen in a controlled manner and on-demand, different supported [32][33][34] and unsupported metal nanoparticles (NPs) have been investigated. 13,15,28 First of all, noble metals such as Ir 29,35 and Rh 10,36 performed well as reforming catalysts. Nevertheless, due to its cost and synergetic catalytic properties, Ni was introduced as the second metal providing superior activity and selectivity.…”

“…12,13 Currently, the N 2 H 4 exothermic decomposition is employed as a propellant in aerospace applications, i.e., in rockets and artificial satellites. 14,15 N 2 H 4 possesses a hydrogen content of 12.5 wt% 16 and decomposes into a mixture of ammonia, hydrogen and This journal is © the Owner Societies 2022 nitrogen in the presence of catalysts such as Shell 405 (30 wt% Ir/Al 2 O 3 ). 17,18 N 2 H 4 decomposition occurs in two different pathways: [19][20][21] N 2 H 4 -N 2 (g) + 2H 2 (g) DH1 = À95.4 kJ mol À1 (1) 3N 2 H 4 -N 2 (g) + 4NH 3 (g) DH1 = À157.0 kJ mol À1 (2)…”
