Abstract (en)
[origin: WO9622954A1] Novel methods for processing gas generant compositions to produce feed stock are disclosed. The methods of the present invention include utilizing a binding agent and other additives in a mixture of ingredients of gas generant compositions in sufficient quantities that the ingredients of the gas generating material will agglomerate to form granules as the ingredients are mixed. Processing methods, including roll coating, continuous mixing, static mixing, freeze drying, solvent extraction, emulsification, azeotropic distillation, spray drying, fluidized bed processing and particle grinding are also disclosed for use in preparing feed stock for final gas generant products. The methods of the present invention are particularly useful in processing gas generating materials having a non-azide based fuel.
