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 (54)

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

the first composition comprises 50-70% of the oil and 30-50% of the wax by volume;

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

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% to 80% 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 90 to 100% of the second mixture (w/w) comprises C 4 -C 20 hydrocarbons;

the wax has:

a number average molecular weight and/or a weight average molecular weight of from 300 to 400 Daltons;

a Reid Vapor Pressure of 12.5 psig or less;

a final boiling point of 950° F. to 1300° F.;

a pour point of 30° F. to 60° F.;

a total chloride content of 50 ppm or less;

a nitrogen content of 300 ppm or less;

a silicon content of 125 ppm or less;

a sodium content of 150 ppm or less;

an iron content of 10 ppm or less;

a phosphorus content of 50 ppm or less;

a sulfur content of 500 ppm or less;

a calcium content of 50 ppm or less;

or a combination thereof;

and the oil has:

a number average molecular weight and/or a weight average molecular weight of from 50 to 350 Daltons;

a Reid Vapor Pressure of 12.5 psig or less;

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 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 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 10 ppm or less.

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

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