Abstract: This disclosure provides a method and system for desulfurizing fuel produced from pyrolysis of waste tires including adsorbing one or more polar sulfur molecules from the tire pyrolysis oil with a regenerable adsorbent, distilling the tire pyrolysis oil to separate the tire pyrolysis oil into at least two fuel products and regenerating and reusing the regenerable adsorbent material. By combining adsorption with distillation, and advantageously recycling byproducts, the methods of this disclosure allow for conversion of waste tires into fuel in a manner that is commercially viable and sustainable.

Abstract: A method and system desulfurizes fuel produced from pyrolysis of waste tires and includes hydroprocessing tire pyrolysis oil to desulfurize the tire pyrolysis oil and obtain a hydroprocessed pyrolysis oil. The hydroprocessed oil is distilled into at least two environmentally fuel products selected from the group consisting of kerosene, naphtha, fuel oil, fuel and diesel. By combining hydroprocessing with distillation, and advantageously recycling byproducts, the methods of this disclosure allow for conversion of waste tires into fuel in a manner that is commercially viable and sustainable.
