Description

BLENDED FUEL COMPOSTIONS INCLUDING PLASTIC PYROLYSIS OIL AND

METHODS OF MAKING- THEREOF

FIELD

[0001] The present disclosure relates to blended fuel compositions that include plastic pyrolysis oil including the total liquid product or a traction thereof as a blending fuel and methods of making thereof.

BACKGROUND

[0002 ] For high quality recycling that leads to plastic products that can again be mechanically recycled, plastic waste must be separated by polymer type and thoroughly cleaned. Typically, plastic waste is not properly segregated and is, consequently, downgraded into inferior products that then cannot be mechanically recycled further and often will later be incinerated (Waste-to- Energy) or discarded into a landfill or the environment.

[0003] An alternative to discarding plastic waste into landfills or mechanically recycling plastic waste is pyrolysis. Pyrolysis of plastic waste typically involves heating the plastic waste and entrained organic material in a low oxygen environment. Depending on the conditions of pyrolysis, a plastic pyrolysis oil having a broad boiling range can be obtained. Said plastic pyrolysis oil, typically with additional purification processing, can be used as at least a portion of a blendstock for upgrading to plastic polymer. This pyrolysis processing provides a plastic blendstock for a more circular plastic economy.

[0004] While there are many applications for plastic pyrolysis oil, applications that require minimal or no further processing after pyrolysis would the most economically beneficial while stil l providing a path to a more circular plastic economy.

SUMMARY

[0005] The present disclosure relates to blended fuel compositions that include plastic pyrolysis oil including the total liquid product or a fraction thereof as a blending fuel.

[0006] A first nonlimiting example method of making a blended fuel composition of the present disclosure comprises: blending a plastic pyrolysis oil with a blendstock fuel to produce a blended fuel composition, wherein the blended fuel composition comprises about 1 vol% to about 20 vol% of the plastic pyrolysis oil and about 80 vol% to about 99 vol% of the blendstock fuel, and wherein a combination of the plastic pyrolysis oil and the blendstock fuel is selected from the group consisting of: a naphtha fraction of the plastic pyrolysis total liquid product and gasoline; a distillate fraction of the plastic pyrolysis total liquid product and diesel; the distillate fraction of the plastic pyrolysis total liquid product and a marine fuel; a heavy pyrolysis fuel fraction of the plastic pyrolysis total liquid product and the marine fuel; and the plastic pyrolysis total liquid product and the marine fuel.

[0007] A nonlimiting example of a blended fuel composition of the present disclosure comprises: about 1 vol% to about 20 vol% of a plastic pyrolysis oil and about 80 vol% to about 99 vol% of the blendstock fuel, and wherein a combination of the plastic pyrolysis oil and the blendstock fuel is selected from the group consisting of: a naphtha fraction of the plastic pyrolysis total liquid product and gasoline; a distillate fraction of the plastic pyrolysis total liquid product and diesel; the distillate fraction of the plastic pyrolysis total liquid product and a marine fuel; a heavy pyrolysis fuel fraction of the plastic pyrolysis total liquid product and the marine fuel; and the plastic pyrolysis total liquid product and the marine fuel.

DETAILED DESCRIPTION

[0008] The present disclosure relates to blended fuel compositions that include plastic pyrolysis oil including the total liquid product or a fraction thereof as a blending fuel. Advantageously, the plastic pyrolysis oil described herein has a low oxygen content, a low sulfur content, and a high hydrocarbon content. Such a composition allows for the plastic pyrolysis oil (total liquid product or fractions thereof) to be blended with blendstock fuels (e.g., marine fuel, gasoline, diesel, and the like), which have low-sulfur requirements and low-oxygen preferences. Further, the plastic pyrolysis oil described herein can be used as-produced (the total liquid product) or as a distilled fraction thereof depending on the end-product fuel.

[0009] Typically, fuels are blended with other hydrocarbon liquids to produce a blended fuel composition having desired properties.. The blending hydrocarbons (e.g., light cycle oil and straight run automotive diesel) often are produced using catalytic cracking of crude oil or other fossil fuel sources. The present disclosure proposes to use plastic pyrolysis oil (total liquid product or fractions thereof) as the blending hydrocarbon. Blending hydrocarbons produced from crude oil and other fossil fuels can have high sulfur concentrations (depending on the source of the crude oil) but a lower cetane index, higher viscosity, and higher density as compared to the plastic pyrolysis oils described herein. Because of the lower cetane index, higher viscosity, and higher density, more fossil fuel-derived blending hydrocarbons (as compared to the plastic pyrolysis oils described herein) are needed to achieve the desired properties of the resultant blended fuel composition. However, the sulfur content can limit the amount of the fossil fuel-derived blending hydrocarbon that can be used. Alternatively, additional desulfurization must be performed before blending. Therefore, the plastic pyrolysis oils described herein provide low-sulfur advantages (e.g., more can be added, if needed, without exceeding the final composition sulfur specifications) as well as high cetane index, lower viscosity, and lower density advantages (e.g., less plastic pyrolysis oil can be used to achieve the desired fuel properties). This provides enhanced versatility in the application of plastic pyrolysis oils in fuel blending. For example, naphtha, distillate, and heavy pyrolysis fuel fractions of the total liquid product of a plastic pyrolysis oil can be blended into gasoline, diesel, and marine fuel, respectively.

[0010] Other organic and biomass pyrolysis oils have been used in the production of fuel products. For example, pyrolysis of organic blendstocks like cellulose can produce broad boiling range hydrocarbon species. However, because of the blendstock composition, the resultant pyrolysis oil has a higher oxygen content, which limits the amount of said pyrolysis oil that can be included in the fuel product. In contrast, the plastic pyrolysis oil contains very low oxygen and sulfur, which allows for the plastic pyrolysis oil or a distillate thereof to be blended directly into fuel without additional purification (e.g., sulfur removal) and to be blended into the fuel at higher concentrations.

[0011] All additional benefit of the use of plastic pyrolysis oil is that the rigorous requirements for mechanical recycling (e.g., separation of each plastic type and stringent pre-cleaning) are not required. Rather, several types of plastic can be pyrolyzed simultaneously with little to no precleaning because the organic matter (e.g., food) carried along with the plastic waste is also pyrolyzed.

Table 12

- Not measured

[0073] Table 12 illustrates that a distillate fraction of plastic pyrolysis total liquid product can be blended with an ultra-low sulfur diesel to increase the cetane index and decrease the density while minimally increasing the sulfur content. In contrast, fossil fuel-derived blending hydrocarbons would likely need io undergo significant and cosily desulfurization to be used with ultra-low sulfur diesel. Further, said fossil fuel-derived blending, hydrocarbons would likely have a higher density (e.g,, Table 1 and Table 2) and the reduction in density benefits of Table 3 would not be realized. Table 13

[0074] Fable 13 illustrates that the naphtha traction of plastic pyrolysis total, liquid product can be blended with gasoline fuel to reduce the density.

[0075] Tables 3-13 illustrate that plastic pyrolysis (total liquid product or a .fraction thereof) can be blended with a variety of blendstock fuels (e.g., marine fuel, naphtha fuel, and diesel) in varying concentrations, including at 15 vol%, to tune the density, viscosity, and other properties while producing a blended fuel with an acceptable low sulfur content (which in many cases is a reduced sulfur content).
