PROBLEM TO BE SOLVED: To produce a carbonaceous material used in a sintering process in an iron producing process. SOLUTION: Two-stage reactors of a lower gas stream layer gasification oven and an upper gas stream layer thermal decomposition oven are used. In the gasification oven, oxygen or oxygen and steam are charged together with coal, and gasified gas is generated by partial oxidation of the coal. In the thermal decomposition oven, coal is charged and the coal is thermally decomposed by sensible heat of the gasified gas moved from the gasification oven to generate pyrolysis char and thermal decomposed gas. The pyrolysis char is recovered and the recovered char is used as the carbonaceous material in a sintering raw material process in the iron producing process. COPYRIGHT: (C)2010,JPO&INPIT
