Abstract

A method of generating oxygen includes introducing a hydrogen peroxide solution (at least 39.5%) into a reactor that has a passage, an oxygen outlet at one end of the passage, a water outlet at another end of the passage, and an inlet between the ends of the passage. Silver flakes are packed tightly within the passage forming interstices to accommodate fluid flow in a substantially restricted manner such that substantial fluid flow only occurs under influence of a pressure differential in the passage that exceeds a predetermined threshold value associated with the fluid. The silver flakes catalyze a decomposition reaction of the hydrogen peroxide into water and oxygen. The hydrogen peroxide and the decomposition reaction move in a stepwise, periodic manner through the interstices from the inlet toward the water outlet. The oxygen and water vapor flow toward the oxygen outlet.

Dependent claims

A method of generating oxygen, the method comprising:

introducing a solution comprising hydrogen peroxide into a reactor that comprises:
an elongated internal passage;
an oxygen outlet at a first end of the elongated internal passage;
a water outlet at a second end of the elongated internal passage;
and
an inlet for the introduction of the solution comprising hydrogen peroxide in a middle portion of the elongated internal passage, wherein the middle portion of the elongated internal passage is between the first end and the second end;
and
silver flakes packed tightly within and substantially filling the elongated internal passage from the first end to the second end, wherein the silver flakes form interstices between and around the silver flakes to accommodate fluid flow through the elongated internal passage, wherein the interstices are configured to accommodate fluid flow through the elongated internal passage in a substantially restricted manner such that substantial fluid flow only occurs under influence of a pressure differential in the elongated internal passage that exceeds a predetermined threshold value associated with the fluid;
catalyzing a decomposition reaction of the hydrogen peroxide into water and oxygen with the silver flakes inside the elongated internal passage;
causing the hydrogen peroxide and the decomposition reaction to move in a stepwise, periodic manner through the interstices in the elongated internal passage from the inlet toward the water outlet by periodically opening a first valve connected to the water outlet;
and
enabling the oxygen and a water vapor produced by the decomposition reaction to flow through the interstices toward the oxygen outlet,
wherein the solution comprising hydrogen peroxide comprises at least 39.5% hydrogen peroxide.
