OZONE OXIDATIVE DECOMPOSITION TREATMENT METHOD FOR VOCS AND/OR GASEOUS INORGANIC REDUCING COMPOUNDS IN GAS

Title:

OZONE OXIDATIVE DECOMPOSITION TREATMENT METHOD FOR VOCS AND/OR GASEOUS INORGANIC REDUCING COMPOUNDS IN GAS

Document Type and Number:

WIPO Patent Application WO/2017/056517

Kind Code:

A1

Abstract:

An ozone oxidative decomposition treatment method for VOCs and/or gas phase inorganic reducing compounds in gas is provided which, being a method that uses a high silica adsorbent to perform oxidative decomposition treatment of VOCs, etc., with ozone, further improves efficiency of oxidative decomposition reaction with ozone, can perform efficient decomposition treatment even of substances at low concentrations such as VOCs and malodorous substances in a high air-flow discharge gas, and which can also reduce the amount of ozone used. When adding and mixing an ozone gas with a gas containing VOCs, then contacting the mixture with a high silica adsorbent, which is a filled porous body, and performing decomposition treatment on the VOCs by ozone oxidation, the aforementioned high-silica adsorbent is the base material in the fill material, and as the base material, a porous substance is used which supports fine particulate powder of a transition metal-containing oxide having a BET specific ratio surface area of 80m2 or greater.
