- Claim: 1. A shaped adsorbent material comprising: an admixture of a binder and an activated adsorbent powder having a butane activity (pBACT) of at least about 50 g/100 g, derived by grinding an activated adsorbent precursor, wherein the admixture is shaped into a form, wherein the shaped adsorbent material has an ASTM BWC of at least 13 g/dL, and at least one of: (i) a ratio of pore volumes of 0.05-1 micron to 0.05-100 microns that is greater than about 80%, (ii) a ratio of pore volumes of 0.05-0.5 micron to 0.05-100 microns that is greater than about 50%, or (iii) a combination thereof.
- Claim: 2. The shaped adsorbent material of claim 1 , wherein the activated adsorbent precursor is an activated carbon precursor.
- Claim: 3. The shaped adsorbent material of claim 1 , wherein the binder comprises at least one of an organic binder, an inorganic binder or a combination thereof.
- Claim: 4. The shaped adsorbent material of claim 3 , wherein the organic binder is at least one of carboxymethyl cellulose (CMC), a synthetic organic binder or a combination thereof.
- Claim: 5. The shaped adsorbent material of claim 3 , wherein the inorganic binder is a clay.
- Claim: 6. The shaped adsorbent material of claim 2 , wherein the activated carbon precursor is derived from at least one of wood, wood dust, wood flour, cotton linters, peat, coal, coconut, lignite, carbohydrates, petroleum pitch, petroleum coke, coal tar pitch, fruit pits, fruit stones, nut shells, nut pits, sawdust, palm, vegetables, a synthetic polymer, natural polymer, lignocellulosic material, or a combination thereof.
- Claim: 7. The shaped adsorbent material of claim 1 , wherein the form is selected from a pellet, a granule, a sphere, a honeycomb, a monolith, a cylinder, a particulate, a hollow-cylinder, a star, a twisted spiral, a asterisk, a configured ribbon, or a combination thereof.
- Claim: 8. A shaped adsorbent material comprising: an admixture of a binder and an activated adsorbent powder having a butane activity (pBACT) of at least about 50 g/100 g, derived by grinding an activated adsorbent precursor, wherein the admixture is shaped into a form, wherein the shaped adsorbent material has an ASTM BWC of at least 13 g/dL, and at least one of: (i) a ratio of pore volumes of 0.05-1 micron to 0.05-100 microns that is greater than about 80%, and (ii) a ratio of pore volumes of 0.05-0.5 micron to 0.05-100 microns that is greater than about 50%.
- Claim: 9. The shaped adsorbent material of claim 8 , wherein the activated adsorbent precursor is an activated carbon precursor.
- Claim: 10. The shaped adsorbent material of claim 8 , wherein the binder comprises at least one of an organic binder, an inorganic binder or a combination thereof.
- Claim: 11. The shaped adsorbent material of claim 10 , wherein the organic binder is at least one of carboxymethyl cellulose (CMC), a synthetic organic binder or a combination thereof.
- Claim: 12. The shaped adsorbent material of claim 10 , wherein the inorganic binder is a clay.
- Claim: 13. The shaped adsorbent material of claim 9 , wherein the activated carbon precursor is derived from at least one of wood, wood dust, wood flour, cotton linters, peat, coal, coconut, lignite, carbohydrates, petroleum pitch, petroleum coke, coal tar pitch, fruit pits, fruit stones, nut shells, nut pits, sawdust, palm, vegetables, a synthetic polymer, natural polymer, lignocellulosic material, or a combination thereof.
- Claim: 14. The shaped adsorbent material of claim 10 , wherein the form is selected from a pellet, a granule, a sphere, a honeycomb, a monolith, a cylinder, a particulate, a hollow-cylinder, a star, a twisted spiral, a asterisk, a configured ribbon, or a combination thereof.
