Abstract
Official abstract text for this publication.
Mesoporous activated carbon having a mesopore structure of at least about 10%. In at least some embodiments, the activated carbon may be coconut shell-based. The enhanced activated carbon may have an intraparticle diffusion constant of at least about 40 mg/g/hr 1/2 .
First claim
Opening claim text (preview).
What is claimed is: 1. A coconut shell-based activated carbon having an intraparticle diffusion constant of at least about 40 mg/g/hr 1/2 and associated with a contact pH level of about 9 to about 10. 2. The coconut shell-based activated carbon of claim 1 having an intraparticle diffusion constant of at least about 100 mg/g/hr 1/2 . 3. The coconut shell-based activated carbon of claim 1 having an apparent density of about 0.43 g/cc to about 0.49 g/cc. 4. The coconut shell-based activated carbon of claim 1 having an iodine number of about 1000 mg/g or greater. 5. The coconut shell-based activated carbon of claim 1 , wherein the coconut shell-based activated carbon is reactivated carbon. 6. A coconut shell-based activated carbon having an intraparticle diffusion constant of at least about 40 mg/g/hr 1/2 , wherein the coconut shell-based activated carbon is reactivated carbon. 7. The coconut shell-based activated carbon of claim 6 having an intraparticle diffusion constant of at least about 100 mg/g/hr 1/2 . 8. The coconut shell-based activated carbon of claim 6 having an apparent density of about 0.43 g/cc to about 0.49 g/cc. 9. The coconut shell-based activated carbon of claim 6 having an iodine number of about 1000 mg/g or greater. 10. The coconut shell-based activated carbon of claim 6 associated with a contact pH level of about 9 to about 10.
