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.
Claims24
A method of desulfurizing fuel produced from pyrolysis of waste tires comprising:
- a) providing a tire pyrolysis oil obtained from pyrolyzed waste tires;
- b) hydroprocessing the tire pyrolysis oil to desulfurize the tire pyrolysis oil and obtain a hydro-processed pyrolysis oil;
- and
- a) distilling the hydro-processed oil into at least two fuel products selected from the group consisting of kerosene, naphtha, fuel oil, fuel and diesel.
A system that desulfurizes tire pyrolysis oil comprising:
- a) a hydroprocessor configured to desulfurize the tire pyrolysis oil to obtain a hydro-processed pyrolysis oil;
- and
- b) a distillation column configured to distill the hydro-processed pyrolysis oil supplied from the hydroprocessor to obtain at least two fuel products selected from the group consisting of kerosene, naphtha, fuel oil, fuel and diesel.
A method of desulfurizing fuel produced from pyrolysis of waste tires comprising:
- a) providing a tire pyrolysis oil obtained from pyrolyzed waste tires;
- b) hydroprocessing the tire pyrolysis oil to desulfurize the pyrolysis oil and obtain a hydro-processed pyrolysis oil;
- c) distilling the hydro-processed oil into at least one fuel product selected from the group consisting of kerosene, naphtha, fuel oil, fuel and diesel;
