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.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.] A method for preparing gas generant feed stock, comprising the steps of:obtaining a desired quantity of ingredients measured in predetermined ratios according to the composition of a gas generating material having a non-azide based fuel;introducing the ingredients into an inlet end of a fluidized bed;supplying fluid media through the fluidized bed to mix the ingredients together;introducing a solvent into the ingredients while continuing to mix the ingredients to cause the ingredients to agglomerate;urging the ingredients to a drying zone; andremoving the solvent from the ingredients after sufficient agglomeration has occurred.
