The amount of waste tires in the world has also reached billions, causing huge black pollution. In order to change black garbage into black gold ore, the resource recycling technology of waste tires is researched as a major topic in the world at home and abroad. The thermal cracking of the waste tires refers to an irreversible thermochemical reaction in which organic matters in the waste tires are cracked by high temperature in an oxygen-free or oxygen-deficient atmosphere to escape volatile products and form solid coke. The percentage content of the pyrolysis product of the tire is as follows: 40% -50%, carbon black: 30% -35%, steel wire: 10% -15%, fuel gas: 8 to 12 percent, so that the whole body of the waste tire is treasure after thermal decomposition. The tire can form gas, liquid and solid products in the incomplete thermal degradation process, and the method can be used for completely cracking the waste tire into useful products such as pyrolysis oil, pyrolysis carbon black, pyrolysis gas and the like.
