Abstract
A gas generating composition which is capable of significantly reducing the concentration of harmful gas components, particularly carbon monoxide, in the generated gas. Also a process for molding a gas generating composition in a suitable shape with high efficiency without a risk of explosion, fire or the like, the process being capable of producing a durable and firm molded gas generating composition. The gas generating composition of the invention contains an oxide-based catalyst comprising at least two members selected from the elements of Groups I, IV, V, VI, VII and VIII in the periodic table in addition to the nitrogen-containing organic compound and the oxygen-containing inorganic oxidizing agent both essentially incorporated in the gas generating composition. The invention also provides a process for molding a gas generating composition, the process comprising the steps of adding 5 to 20% by weight of water to a gas generating composition essentially containing a nitrogen-containing organic compound and an oxyhalogen acid salt and further containing an oxide-based catalyst to give a wet mixture, granulating the wet mixture into wet granules, drying the wet granules to provi…
