GENERATION OF LOW-TEMPERATURE GAS FROM SOLID FUEL Russian patent published in 2001 - IPC

FIELD: generation of low-temperature gas, not above 350 C, for example nitrogen with solid monolithic charge having through pores for passage of charge combustion products. SUBSTANCE: size of pores ensures reduction of temperature of gas in passing through pores to preset magnitude. Composition for generation of low-temperature nitrogen is based on sodium azide, sodium nitrate, binder and metal halide. In preparing gas-generating charge, powder-like components of charge are mixed, solvent is introduced till plastic material is formed, mass thus obtained is forced through, molded and change is hardened. EFFECT: possibility of obtaining nitrogen of required purity at reduced temperature. 2 cl, 3 dwg, 1 tbl
