A technique for preparing fuel oil and carbon blank through waste tires comprises the steps that (1) the waste tires are crushed into particles after metal and fiber impurities in the waste tires are removed; (2) the waste tires, hydrogen peroxide and water are added into a reactor, the concentration of the hydrogen peroxide is kept 6-9.5 wt%, and the reactor is sealed; (3) the reactor is heated and pressurized till the water is in the supercritical or subcritical state, and the reaction is conducted for 45-75 min; (4) solid-liquid separation is conducted on reactants, and solid is the carbon black; and (5) liquid is extracted through dichloromethane, so that the fuel oil is obtained. By adoption of the treatment method, 3.50%-7.5% of the fuel oil can be obtained, 23%-43% of the solid carbon black can be obtained, and the removal rate of waste tire treatment can reach 80% or over. 本发明公开了种废旧轮胎制备燃油和炭黑的工艺，包括：(1)废旧轮胎去除金属、纤维杂物后，破碎成颗粒；(2)将废旧轮胎、过氧化氢和水加入反应器，使得过氧化氢浓度保持在6-9.5wt％，密封反应器；(3)反应器升温加压到水的超临界或亚临界状态下，反应45-75min
