<P>PROBLEM TO BE SOLVED: To provide an inexpensive and high-yield carbonization type graphite production method capable of treating a waste tire in whole and sintering the contained carbon component, thereby recyclably and inexpensively producing graphite in a high yield. <P>SOLUTION: The waste tire is heated at high temperature under a non-oxygen state within a heat-resisting furnace as it is without being broken. Thus, the tire is thermally decomposed, and is separated into mixed gas components to be vaporized and mixed solid components remaining in the furnace without being vaporized. Thereafter, flame is projected on the remaining mixed solid components with a burner, so as to burn away inflammable solid components. Next, lightweight ash components and metal components are separated away from nonflammable components remaining in the furnace, and the remaining carbon component is sintered. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
