Title:
SYSTEM FOR DEGRADING AND REMOVING TOXIC SUBSTANCE BY MEANS OF THERMAL EXCITATION OF CHROMIUM OXIDE OR NICKEL OXIDE
Document Type and Number:
WIPO Patent Application WO/2010/061854
Kind Code:
A1
Abstract:
Disclosed is a system for degrading and removing a toxic substance by introducing a gas containing the toxic substance into a reaction apparatus and causing the gas to contact with a heated oxide semiconductor. The system is characterized in that a porous material having chromium oxide or nickel oxide carried thereon is placed in the reaction apparatus as the oxide semiconductor, chromium oxide or nickel oxide on the porous material is thermally excited, and the gas is contacted with chromium oxide or nickel oxide excited on the porous material. It becomes possible to provide a practically highly useful technique for degrading and removing a toxic substance with high degradation/removal efficiency.
