Abstract

Disclosed herein are hydrocarbon based compositions derived from pyrolysis of a feedstock comprising post-consumer and/or post-industrial plastics and methods of making and use thereof.

Claims (57)

1. An oil derived from pyrolysis of a feedstock comprising post-consumer and/or post-industrial plastics, wherein:

the oil is produced at an industrial scale;

the oil has a number average molecular weight and/or a weight average molecular weight of from 50 to 300 Daltons;

the oil comprises a mixture of different hydrocarbons, any of which can optionally be substituted, and the oil comprises 90% to 100% (w/w) of C 4 -C 20 hydrocarbons, and wherein the oil is substantially free of hydrocarbons comprising 30 or more carbons;

the oil has a Reid vapor pressure of 12.5 psig or less; and

the oil has:

a final boiling point of 750° F. to 1000° F.;

a pour point of 0° F. to 20° F.;

a total chloride content of 500 ppm or less;

a nitrogen content of 600 ppm or less;

a silicon content of 2000 ppm or less;

a sodium content of 100 ppm or less;

an iron content of 10 ppm or less;

a phosphorus content of 25 ppm or less;

a sulfur content of 250 ppm or less;

a calcium content of 50 ppm or less;

or a combination thereof.

2. The oil of claim 1 , wherein the mixture comprises:

25-35% C 4 -C 8 hydrocarbons,

55-65% C 9 -C 20 hydrocarbons, and

1-10% C 21 -C 29 hydrocarbons.

3. The oil of claim 1 , wherein the mixture comprises:

90-100 wt. % unsaturated hydrocarbons;

0-5 wt. % unsaturated non-aromatic hydrocarbons; and

0-2.5 wt. % aromatic hydrocarbons.

4. The oil of claim 1 , wherein the oil has a final boiling point of from 750° F. to 1000° F.

5. The oil of claim 1 , wherein the oil has a pour point of from 0° F. to 20° F.

6. The oil of claim 1 , wherein the oil has a total chloride content of 500 ppm or less.

7. The oil of claim 1 , wherein the oil has a nitrogen content of 600 ppm or less.

8. The oil of claim 1 , wherein the oil has a silicon content of 2000 ppm or less.

9. The oil of claim 1 , wherein the oil has a sodium content of 100 ppm or less.

10. The oil of claim 1 , wherein the oil has an iron content of 10 ppm or less.

11. The oil of claim 1 , wherein the oil has a phosphorus content of 25 ppm or less.

12. The oil of claim 1 , wherein the oil has a sulfur content of 250 ppm or less.

13. The oil of claim 1 , wherein the oil has a calcium content of 50 ppm or less.

14. The oil of claim 1 , wherein the oil has a copper content of 10 ppm or less, a nickel content of 250 ppm or less, a vanadium content of 25 ppm or less, or a combination thereof.

15. The oil of claim 1 , wherein the oil has:

a total chloride content of 100 ppm or less;

a nitrogen content of 575 ppm or less;

a silicon content of 250 ppm or less;

a sodium content of 25 ppm or less;

an iron content of 10 ppm or less;

a phosphorus content of 9 ppm or less;

a sulfur content of 10 ppm or less;

a calcium content of 5 ppm or less;

or a combination thereof.

16. The oil of claim 1 , wherein the oil has a water by distillation amount of 0.5 vol. % or less, a total sediment content of 0.5 vol. % or less, an n-heptane insoluble content of 0.1 wt. % or less, a total acid number of 1 mg KOH/g or less, or a combination thereof.

17. The oil of claim 1 , wherein the oil has:

a final boiling point of 750° F. to 1000° F.; and

a pour point of 0° F. to 20° F.

18. The oil of claim 1 , wherein the oil is produced via pyrolysis in a volume of from 10,000 to 1,000,000 gallons per 5 to 90 days.

19. A method of making the oil of claim 1 , wherein the method comprises pyrolysis of a feedstock comprising post-consumer and/or post-industrial plastics.

20. A composition, wherein the composition comprises or is derived from the oil of claim 1 .

21. The composition of claim 20 , wherein the composition comprises a lubricating oil, a mineral oil, a group III base oil, a paraffin wax, a binder, a processing aid, kerosene, white oils, liquefied petroleum gas (LPG), naphtha, diesel and gas oil, gasoline, diesel fuel, asphalt, automotive fuel, aviation fuels, base oil, bitumen, cadalene, cutting fluid, fuel oil, heating oil, heavy fuel oil, hydrocarbon solvents, ligroin, mazut, microcrystalline wax, mineral oil, motor fuel, motor oil, naphthenic acid, petroleum benzine, petroleum ether, petroleum jelly, petroleum naphtha, petroleum resin, retene, or a combination thereof.

22. An article of manufacture, wherein the article of manufacture comprises or is derived from the oil of claim 1 .

23. The article of claim 22 , wherein the article comprises packaging, film, fibers, carpets, clothing, molded articles, extruded pipes, a medical device, lubricant, candles, adhesives, packaging, rubber, cosmetics, fire logs, bituminous mixtures, superficial wear coatings, asphalt, sealing coatings, automotive fuel, aviation fuels, base oil, bitumen, cadalene, cutting fluid, diesel fuel, fuel oil, gasoline, heating oil, heavy fuel oil, hydrocarbon solvents, kerosene, ligroin, mazut, microcrystalline wax, mineral oil, motor fuel, motor oil, naphtha, naphthenic acid, paraffin wax, petroleum benzine, petroleum ether, petroleum jelly, petroleum naphtha, petroleum resin, retene, tar, fertilizer, flooring, perfume, insecticide, soap, vitamin, amino acid, wood-based composites, oriented-strand board (OSB), particleboard, hardboard, medium density fiberboard, gypsum board, crayons, paper and carton coatings, or a combination thereof.
