A portable oxygen generating system using the principle of exothermic catalytic decomposition of an aqueous hydrogen peroxide comprising: a feed tank (1) having a mouth (10) to receive liquid hydrogen peroxide, a cap (12) to seal the mouth (10) during operation and an outlet pipe (3); an on//off valve (5) to control discharge from the feed tank; a regulator valve (7) to stop discharge from the feed tank when pressure in the system is equal to a predetermined pressure; a reactor (9) containing a catalyst of lead strips (30) in which hydrogen peroxide is decomposed; a cooling coil (13) to cool and condense the reaction products; a separator tank (17) to hold liquid water and gaseous oxygen: a return pipe (19) to the feed tank to balance pressure in the system; a drain (20) with a drain valve (21) to discharge water; and a product line (22) to supply oxygen for use by an operator of the system.
