-136. (canceled)
Carbon particles, wherein the carbon particles have:
- a total content of polycyclic aromatic hydrocarbons (PAHs) of less than or equal to about 0.5 parts per million;
- a content of benzo[a]pyrene of less than or equal to about 5 parts per billion;
- and
- (i) a dibutyl phthalate (DBP) absorption that is less than or equal to about 1.3 times greater than a compressed dibutyl phthalate (CDBP) absorption of the carbon particles;
- (ii) a surface area from about 15 m2/g (square meters per gram) to about 300 m2/g;
- and a purity of less than about 0.05% ash, less than about 5 ppm 325 mesh grit, or a combination thereof;
- or (iii) a nitrogen surface area (N2SA) greater than or equal to about 15 square meters per gram (m2/g) and less than about 5 ppm sulfur.
Carbon particles, wherein the carbon particles have:
- a content of polycyclic aromatic hydrocarbons (PAHs) of less than or equal to about 0.5 parts per million, wherein a content of benzo[a]pyrene is less than or equal to about 5 parts per billion;
- a nitrogen surface area (N2SA) of less than or equal to about 50 m2/g;
- and
- a dibutyl phthalate (DBP) absorption of less than or equal to about 131 ml/100 g.
Carbon particles, wherein the carbon particles have a total content of polycyclic aromatic hydrocarbons (PAHs) of less than or equal to about 0.5 parts per million, a content of benzo[a]pyrene of less than or equal to about 5 parts per billion, and a water spreading pressure (WSP) that is less than about 5 mJ/m2.
