The propellant has a short shelf-life because of nitrogen oxides that were released from nitrocellulose decomposition, As-received and surface-modified ACFs were applied to remove the nitrogen oxides with intend to extend the shelf-life of propellant. The specific surface area of modified ACFs was slightly decreased but nitrogen function groups such as pyridine, pyridone and pyrrol were created on the surface of ACFs. As a result the NO removal capacity of the surface-modified ACF by propellant waste increased about twice than that of the as-received ACF. The shelf-life of propellant was extended about 1.25 times by accompanying surface-modified ACF.
