Globally, 150 million waste tires are generated annually. Various technologies have been proposed to utilize tires, including recycling, reuse, and incineration for heat recovery. However, the associated negative environmental impacts hindered industrial application of these methods. Tire pyrolysis, which transforms into fuel, offers an effective approach utilizing discarded tires. Nevertheless, tire pyrolysis oil (TPO) produced by this process is often low quality contains a high sulfur content, restricts its direct use. Current hydrodesulfurization techniques, widely employed eliminate compounds from TPO, expensive intricate. Although emerging oxidative desulfurization technology presents advantages in dealing with that difficult remove via hydrodesulfurization, it also faces challenges such as oxidant cost catalyst selection. TPO has chemical properties similar diesel, energy utilization efficiency can be substantially improved optimizing blending ratio, effectively reducing fuel costs. unsaturated hydrocarbon content affects storage stability, necessitating use further refining processes. The light fractions due their high-octane number, suitable gasoline, but issues nitrogen lead combustion pollution, need addressed. Research indicates distillation conditions enhance recovery rates high-value like limonene, thereby improving economic recycling. This paper reviews methods resource status, discussing prospects fuel. Strategies promote widespread practice, facilitating efficient resources environmentally friendly development.
