PURPOSE:To obtain oxygen conveniently at low pressure and at high temp. inexpensively by packing a deriv. of H2O2 and decomposing catalyst soln. in a waterproof heat insulated pressure resistant vessel provided with a pressure control valve being separated with a partition membrane and mixing the H2O2 deriv. with the decomposition catalyst soln. at the using stage. CONSTITUTION:A deriv. of H2O2 1 (e.g. sodium percarbonate, H2O2 adduct of urea) and a soln. of decomposition catalyst 2 (e.g. aq. soln. of KMnO4, aq. soln. of MnSO4) are packed in a pressure resistant vessel 5 which is made waterproof and heat-insulated and being provided with a pressure control valve 3, separating both with isolating membrane 9 of such as PVC bag, etc. In the using stage, a starting pin 11 is operated to break the seal of the isolating membrane 9 with a knife 10 to bring the H2O2 deriv. 1 into contact with the decomposition catalyst soln. 2 and the reaction I or II, etc., is caused to generator O2. Generated O2 is cooled and purified through a felt layer 6, sintered metal layer 7 and a molecular sieve layer of silica gel 8, etc., and discharged from a discharging port 12.
