Title:
METHOD FOR DECOMPOSING ORGANIC SUBSTANCE INTO LOWER MOLECULES, AND METHOD FOR UTILIZING EXHAUST GAS GENERATED BY METALLURGICAL FURNACE
Document Type and Number:
WIPO Patent Application WO/2012/029283
Kind Code:
A1
Abstract:
A method for decomposing an organic substance into lower molecules is provided. In this method, an organic substance is decomposed into lower molecules and converted into gaseous fuel, liquid fuel, or the like. In this process, the organic substance can be efficiently reformed and decomposed into lower molecules using a stable supply of gas to obtain a reformate containing minimal amounts of heavy fractions or carbonaceous materials and large amounts of light fractions. The method can be implemented using relatively simple equipment. An excess of steam is added to an off-gas (g0) that contains carbon monoxide and is generated by a metallurgical furnace, and a shift reaction is performed to obtain a mixed gas (g) containing the hydrogen and carbon dioxide generated by the shift reaction and the steam not consumed by the shift reaction. The mixed gas (g) is brought into contact with the organic substance, and the organic substance is reformed and decomposed into lower molecules. Reforming of the organic substance involves four simultaneously occurring reactions: hydrogenation, hydrogenolysis, steam reforming, and carbon dioxide reforming, allowing decomposition of the organic substance into lower molecules to be facilitated efficiently even at a relatively low reaction temperature.
