DISPOSAL OF WASTE TIRE AND EQUIPMENT THEREFOR

摘要

PROBLEM TO BE SOLVED: To recover a high quality light gas and light oil having a limited risk of causing environmental pollution, when burned, at a high oil recovery ratio by using a disposal method including specific 2 steps for the disposal of a waste tire. SOLUTION: This disposal method of a waste tire includes a process to carbonize a crushed waste tire and a process in which a pyrolitic gas generated from the foregoing process is lightened and desulfurized simultaneously by a catalytic contact reaction. The catalytic contact reaction to lighten and desulfurize the pyrolitic gas simultaneously in the second process is conducted by using a catalyst in which CoO3 is supported by TiO2 . A preferable disposal method of a waste tire is that, while the catalytic contact reaction is conducted in one line, the regeneration of the catalyst after the lightening and desulfurization is conducted in the other line, and thus the lightening and desulfurization and the regeneration alternate between the two lines.
