Abstract
A porous matrix substrate that has chlorite reactant distributed therein can be used to produce gaseous chlorine dioxide. Ozone-containing gas can pass through the porous matrix substrate and the ozone can react with the chlorite to produce chlorine dioxide.
Claims12
A method of producing gaseous chlorine dioxide, the method comprising:
- passing an ozone-containing gas through a solid porous matrix that includes chlorite reactant distributed therein, and
- reacting the ozone in the ozone-containing gas with the chlorite reactant to produce the gaseous chlorine dioxide.
A system for producing gaseous chlorine dioxide, the system comprising:
- an ozone generator that is configured to produce an ozone-enriched gas;
- and
- a reactor that includes a solid porous polymer matrix with chlorite reactant distributed therein, the reactor being configured to (i) receive the ozone-enriched gas from the ozone generator and (ii) exhaust a gas product including gaseous chlorine dioxide that is produced from reacting the chlorite reactant with ozone in the ozone-enriched gas.
