Study on Catalytic Decomposition of DMAZ Over Iridium Supported Alumina Catalyst

Message:
Abstract:
Hydrazine catalytic propulsion system is the most conventional system in satellite orbit control. Dimethyl amino ethyl azide (DMAZ) is a replacement candidate monopropellant for hydrazine in such systems. Catalyst IR/γ-Al2O3 has been reported for decomposition of DMAZ. However, there is no information about performance conditions of the catalyst. For prediction of decomposition ability of DMAZ by the catalyst, several catalysts with various amounts of IR were prepared and characterized. Then, a micro-reactor was designed to evaluate the catalytic activity. The prepared catalysts were tested and examined at various conditions. The results showed that the increase in temperature of catalytic bed and decrease in space velocity led to an increase in catalytic activity. Also, an optimum amount of 42% in IR showed maximum activity at 205 °C of catalytic bed and 2.82 hr-1 of space velocity.
