<p><P>PROBLEM TO BE SOLVED: To provide a thermal decomposition method for a carbonaceous resource capable of increasing a generated combustible gas by reducing tar by utilizing a characteristic of a shaft type thermal decomposition furnace. <P>SOLUTION: In the thermal decomposition method for the carbonaceous raw material using a move bed shaft type thermal decomposition furnace, after the carbonaceous resource charged from an upper part of the furnace and descending the inside of the furnace is thermally decomposed by a heating gas charged from a lower part of the furnace and ascending the inside of the furnace, a generated solid carbonized material is discharged from the bottom of the furnace and the generated gas and tar are discharged from an upper part of the furnace. The amount of generated tar is reduced by making a ratio of sensible heat of the charged heating gas relative to an amount of the charged carbonaceous resource to 800 Mcal/ton-1,500 Mcal/ton. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
