発明の名称 (英語) METHOD FOR DECOMPOSING PERSISTENT ORGANIC SUBSTANCE USING SUPER-POWERFUL CATALYST, AND SUPER-POWERFUL CATALYST NEW
発明の概要(英語) Provided is a novel method for decomposing an organic substance such as a ligneous material or a synthetic polymer. This method for decomposing an organic substance is characterized in that there are used a catalyst in which a complex formed from a transition metal and a pi-electron-containing organic ligand is supported on an electroconductive material or a semiconductor, and an oxidizing agent.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, the waste disposal in landfills or incineration processing occurs in the environmental problems. In order to solve this problem, the waste processing techniques have been conducted diligent studies.
For example, to Patent Document 1, waste plastic, organic material such as waste wood waste, can be thermally decomposed by heating at a high temperature, thermal decomposition residue on the decomposition gas, oxygen gas and the thermal decomposition reaction and the reforming gas, a harmful component in exhaust gas, waste of the processing method are described.
Among the waste including an organic material, cellulose, lignin, lignocellulose, such as hemicellulose components or wood-based materials, polyethylene, and synthetic polymers such as polyethylene terephthalate typically, chemically stable and hardly decomposable organic matter decomposition of difficult processing techniques are studied.
For example, to Patent Document 2, cellulose, hemicellulose and lignin of wood-based material is decomposed thermally decompose to generate the gas, the reforming gas of the organic waste processing system is described. Patent Document 3 is, the cellulosic biomass comprising cellulose and hemicellulose, high temperature and high pressure of the supercritical state and is decomposed with water, the oligosaccharide or monosaccharide manufacturing have been described.
Patent Document 4 is to, polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride and the like is heated by a heating furnace waste plastic containing the combustible gas is generated, then, in a combustion furnace to burn a combustible gas and the waste processing apparatus, when an abnormality occurs in a combustible gas can be discharged to the waste products of the cement manufacturing apparatus described in the processing apparatus.
Also, use of a catalyst efficiently oxidative decomposition of the organic waste has been provided a technology for processing.
Is Patent Document 5, Fenton reaction utilizing an organic chlorine compounds and decomposition processing of the method, specifically, metal oxide Mn, Fe, Co, Ni or cu-doped using an oxidation catalyst, water and organic chlorine compounds can be decomposed by thermal oxidation has been described. More specifically, a catalyst or catalyst Cu-WO3 using Cu-TiO2, chlorobenzene and chlorophenol to 30mpa, in 200°C water is decomposed by thermal oxidation has been described.
