<P>PROBLEM TO BE SOLVED: To modify tar, generated when a raw material is gasified by a fluidized bed gasification furnace, in the fluidized bed gasification. <P>SOLUTION: A floatage catalyst body 24 whose bulk density is smaller than flowing particles 3 charged to the fluidized bed gasification furnace 1 is charged into a gasification room 2 to form a tar capturing-modifying layer 25 by the floatage catalyst body 24 on an upper surface of a fluidized bed 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
