Abstract

Claims (41)

1. A first composition comprising a wax and an oil, wherein:

the first composition comprises 50% or more of the oil and 30% or more of the wax by volume;

the wax and the oil are each derived from pyrolysis of a feedstock comprising postconsumer and/or post-industrial plastics;

wherein the feedstock comprises 50% or more by weight post-consumer plastics;

wherein the feedstock comprises 90% or more by weight of polyethylene, polypropylene, polystyrene, or a combination thereof;

the wax and the oil are each produced at an industrial scale;

the wax comprises a first mixture of different hydrocarbons, any of which can optionally be substituted, wherein from 60% or more of the first mixture (w/w) comprises C 20 -C 45 hydrocarbons;

the oil comprises a second mixture of different hydrocarbons, any of which can optionally be substituted, wherein from 55% or more of the second mixture (w/w) comprises C 9 -C 20 hydrocarbons;

the wax has:

an iron content of from 0.001 to 2.5 ppm;

and the oil has:

an iron content of from 0.001 to 2.5 ppm.

2. The first composition of claim 1 , wherein the wax has a final boiling point of 950° F. to 1300° F.

3. The first composition of claim 1 , wherein the wax has a pour point of from 30° F. to 60° F.

4. The first composition of claim 1 , wherein the wax has a total chloride content of 50 ppm or less.

5. The first composition of claim 1 , wherein the wax has a nitrogen content of 300 ppm or less.

6. The first composition of claim 1 , wherein the wax has a silicon content of 125 ppm or less.

7. The first composition of claim 1 , wherein the wax has a sodium content of 150 ppm or less.

8. The first composition of claim 1 , wherein the wax has an iron content of from 0.001 to 1 ppm.

9. The first composition of claim 1 , wherein the wax has a phosphorus content of 50 ppm or less.

10. The first composition of claim 1 , wherein the wax has a sulfur content of 500 ppm or less.

11. The first composition of claim 1 , wherein the wax has a calcium content of 50 ppm or less.

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

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

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

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

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

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

18. The first composition of claim 1 , wherein the oil has an iron content of from 0.001 to 1 ppm.

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

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

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

22. A second composition, wherein the second composition comprises the first composition of claim 1 , and wherein the second composition comprises a lubricating oil, a mineral oil, a paraffin wax, a binder, a processing aid, kerosene, white oils, liquefied petroleum gas (LPG), naphtha, kerosene, diesel and gas oil, gasoline, diesel fuel, asphalt, automotive fuel, aviation fuels, base oil, bitumen, cadalene, cutting fluid, fuel oil, heating oil, hydrocarbon solvents, microcrystalline wax, mineral oil, motor fuel, motor oil, naphthenic acid, petroleum ether, petroleum jelly, petroleum resin, retene, or a combination thereof.

23. A method of use of the second composition of claim 22 , wherein the method comprises: feeding the second composition into a petroleum refinery, a catalytic cracking system, a thermal cracking system, a polymerization system, or a combination thereof; and using the second composition as a hydrocarbon feedstock for said petroleum refinery, catalytic cracking system, thermal cracking system, polymerization system, or combination thereof.

24. An article of manufacture, wherein the article of manufacture comprises the first composition of claim 1 .

25. The article of claim 24 , 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, hydrocarbon solvents, jet fuel, kerosene, microcrystalline wax, mineral oil, motor fuel, motor oil, naphtha, naphthenic acid, paraffin wax, petroleum ether, petroleum jelly, 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.
