Abstract

Disclosed in certain embodiments are sorbents for capturing heavy hydrocarbons via thermal swing adsorption processes.

First claim

What is claimed is:

1. A method of treating a fluid volume, the method comprising contacting the fluid volume with a sorbent, wherein:
the fluid volume has an initial concentration of C6+ components prior to the contacting,
the fluid volume has a final concentration of C6+ components after the contacting that is less than the initial concentration of C6+ components,
the sorbent comprises amorphous SiO 2 at a weight percent greater than 90%,
a relative micropore surface area (RMA) of the sorbent is greater than 10%, and
a total pore volume for pores between 500 nm and 20000 nm in diameter is greater than 70 mm 3 /g.

2. The method of claim 1 , wherein the RMA of the sorbent is greater than 15%.

3. The method of claim 1 , wherein the sorbent comprises a fluid-accessible surface having a Brunauer-Emmett-Teller (BET) surface area greater than 500 m 2 /g.

4. The method of claim 1 , wherein the initial concentration of C6+ components is greater than 150 ppm, and wherein the final concentration of C6+ components is less than 30 ppm.

5. The method of claim 1 , wherein the C6+ components comprise one or more of benzene, heptane, octane, nonane, toluene, or ethylbenzene.

6. The method of claim 1 , wherein the sorbent is adapted to remove C5+ components from the fluid volume, wherein the C5+ components comprise neopentane.

7. The method of claim 1 , wherein the sorbent is in a form of beads that form a sorbent bed, wherein a size of the beads is from 2.4 mm to 4 mm.

8. The method of claim 1 , wherein the contacting occurs in a thermal swing-adsorption system.

9. A method of treating a fluid volume, the method comprising contacting the fluid volume with a sorbent, wherein:
the fluid volume has an initial concentration of C6+ components prior to the contacting,
the fluid volume has a final concentration of C6+ components after the contacting that is less than the initial concentration of C6+ components,
the sorbent comprises amorphous SiO 2 at a weight percent greater than 90%,
a total pore volume for pores between 500 nm and 20000 nm in diameter is greater than 100 mm 3 /g, and
an RMA of the sorbent is greater than 15%.

10. The method of claim 9 , wherein the sorbent comprises a fluid-accessible surface having a Brunauer-Emmett-Teller (BET) surface area greater than 500 m 2 /g.

11. The method of claim 9 , wherein the initial concentration of C6+ components is greater than 150 ppm, and wherein the final concentration of C6+ components is less than 30 ppm.

12. The method of claim 9 , wherein the C6+ components comprise one or more of benzene, heptane, octane, nonane, toluene, or ethylbenzene.

13. The method of claim 9 , wherein the sorbent is in a form of beads that form a sorbent bed, wherein a size of the beads is from 2.4 mm to 4 mm.

14. The method of claim 9 , wherein the contacting occurs in a thermal swing-adsorption system.

15. A thermal swing adsorption system comprising a sorbent bed comprising a sorbent, the sorbent comprising amorphous SiO 2 at a weight percent greater than 90%, wherein a relative micropore surface area (RMA) of the sorbent is greater than 10%, and wherein a total pore volume for pores between 500 nm and 20000 nm in diameter is greater than 70 mm 3 /g.

16. The thermal swing adsorption system of claim 15 , wherein the thermal swing adsorption system is adapted for adsorption of C6+ components from a fluid volume, wherein the C6+ components comprise one or more of benzene, heptane, octane, nonane, toluene, or ethylbenzene.

17. The thermal swing adsorption system of claim 15 , wherein the thermal swing adsorption system is adapted to remove C5+ components from a fluid volume, wherein the C5+ components comprise neopentane.
