Abstract
A sorbent composition comprising primarily activated carbon with an apparent density of at least about 0.30 g/cc, wherein the sorbent composition comprises small mesopores, wherein the small mesopores have a pore size ranging from about 20 Å to about 150 Å, wherein a volume of small mesopores is at least about 0.10 cc/g, wherein the sorbent composition comprises micropores, wherein the micropores have a pore size of less than about 20 Å, wherein a volume of micropores is at least about 0.35 cc/g, and wherein the sorbent comprises from about 10 vol. % to about 35 vol. % solid activated carbon.

A sorbent composition comprising primarily activated carbon with an apparent density of at least about 0.30 g/cc, wherein the sorbent composition comprises small mesopores, wherein the small mesopores have a pore size ranging from about 20 Å to about 150 Å, wherein a volume of small mesopores is at least about 0.10 cc/g, wherein the sorbent composition comprises micropores, wherein the micropores have a pore size of less than about 20 Å, wherein a volume of micropores is at least about 0.35 cc/g, and wherein the sorbent comprises from about 10 vol. % to about 35 vol. % solid activated carbon.
A method comprising treating a contaminated medium with a sorbent composition comprising greater than about 90 wt % bituminous coal, less than about 0.5 wt % green strength binder, and less than about 2 wt % moisture, wherein the sorbent composition comprises sequestration pores, wherein the sequestration pores have a pore size of about 1 to about 2 times the molecular diameter of a target contaminant, wherein the sorbent composition has an apparent density of at least about 0.30 g/cc, and wherein the sequestration pore volume is at least about 0.15 cc/g.
