Analysis and Purification of the Combustion Gas of Gas Generant

Four kinds of gas generant compositions comprised of 5-aminotetrazole nitrate(5-ATN) as the oxidizing component are provided. The combustion gases are determined through qualitative and quantitative analysis by gas chromatograph, ultraviolet spectrophotometer and a comprehensive system of flue gas analyses. The main components of the combustion gas are N2, CO2 and H2 as well as a small amount of CO, NOx and NH3. Hopcalite is selected as purifying agent, and the results of experiments show that the agent can remove all of the CO and reduce the content of NOx to 100 mg·m-3, NH3 to 10 mg·m-3.
