An ozone converter includes an outer housing having an inlet and an outlet and a core disposed within the outer housing, the core including a central passageway formed therein and passing thorough the core. The converter also includes an ozone control assembly that allows air to pass through the central passageway in an closed mode and prevents flow thorough the central passageway in an open mode, the assembly including cover flaps that cover a portion of the core in the closed mode and that do not cover the core in the open mode.

A device for generating singlet oxygen is provided. The device has elongated posts extending from a surface, the lateral sides of which have particles with a sensitizer that converts triplet oxygen to single oxygen upon exposure to light. An optical fiber conveys light to the sensitizer and a gas supply tube conveys oxygen to the sensitizer. The device is configured to keep the sensitizer from contacting external fluids, such as saliva.

An ozone converter includes a toroidal shaped inlet housing and an outlet housing that is removably coupled to the inlet housing. The converter also includes a ring shaped ozone removable core disposed at least partially within the inlet housing.

Removing waste gas, more particularly carbon dioxide, from a gaseous medium and producing gaseous oxygen, a recovered waste constituent, more particularly solid carbon, heat and electrical power, by means of chemical reaction of waste gas with a metal oxide, more particularly dodecatungstophosphoric acid, immobilized in a porous matrix, more particularly tetraethylorthosilicate sol gel, enclosed in a gas permeable membrane. Regeneration of the metal oxide, more particularly by heating, and reconstitution of the porous matrix containing same by periodic introduction of base materials, and in some cases with externally supplied energy.

The present invention relates to a composition for generating oxygen, comprising at least one oxygen source selected from chlorates and perchlorates, to an oxygen generator comprising such a composition, and a method for generating oxygen by decomposing such a composition. The present invention further relates to the use of transition metal ortho-phosphate compounds ortho-vanadate compounds and mixed ortho-phosphate-vanadate compounds as multifunctional components in the oxygen generating compositions.

The present disclosure relates to methods and reactors for generating of gas and specifically for generation of oxygen gas and hydrogen gas.

A zero-emission, closed-loop and hybrid solar-produced syngas power cycle is introduced utilizing an oxygen transport reactor (OTR). The fuel is syngas produced within the cycle. The separated oxygen inside the OTR through the ion transport membrane (ITM) is used in the syngas-oxygen combustion process in the permeate side of the OTR. The combustion products in the permeate side of the OTR are CO.sub.2 and H.sub.2O. The combustion gases are used in a turbine for power production and energy utilization then a condenser is used to separate H.sub.2O from CO.sub.2. CO.sub.2 is compressed to the feed side of the OTR. H.sub.2O is evaporated after separation from CO.sub.2 and fed to the feed side of the OTR.
