Process of sodium peroxide production

A method for producing sodium peroxide (Na2O2) which method is characterized by pulverizing oxygen gas (O2 (g)) onto molten metallic sodium (Na) for oxidation under nitrogen gas (N2 (g)) blanket in order to increase the purity of the sodium peroxide in a reactor vessel closed to atmospheric conditions;

• Wherein the oxidation reaction of molten sodium is set to occur in a temperature range of 200° C. to 450° C.
• Wherein the oxidized sodium as sodium monoxide is continued to be retreated with oxygen as the second stage of oxidation by agitating molten metallic sodium and sodium monoxide mixture in a closed vessel under
• Nitrogen gas blanket at a temperature range of 250° C. to 450° C.
• Wherein the two oxidation stages are occurred in a single vessel.
• Wherein the source of sodium is pure sodium metal, or sodium salt, sea water, or sodium hydroxide or sodium containing chemical compound including brine mixture (i.e. NaCl and CaCl2).
• Wherein the said reactor vessel is free from air and isolated from water condensation which is filled with nitrogen gas (N2 (g)).
• Wherein the oxygen is pulverized as a gas mixture of Oxygen and Nitrogen.
• Wherein the reactor vessel is operated under vacuum pressures for enabling the lower melting point for sodium metal with lower start-up temperatures below 98° C.
• Wherein the complete mass of metallic sodium is injected to the reactor tank at once before starting the oxidation process or is injected in portions during the oxidation reaction starts.
• Wherein the production rate and batch size is controlled by the flow of sodium production process and flow of molten sodium and flow of oxygen gas into the reactor without interrupting the whole process cycle.
