HIGHLY MESOPOROUS ACTIVATED CARBON
Highly mesoporous activated carbon products are disclosed with mesoporosities characterized by mesopore volumes of 0.7 to 1.0 cubic centimeters per gram or greater. Also disclosed are activated carbon products characterized by a Molasses Number of about 500 to 1000 or greater. Also disclosed are activated carbon products characterized by a Tannin Value of about 100 to 35 or less. The activated carbon products may be further characterized by total pore volumes of at least 0.85 cubic centimeters per gram and BET surface areas of at least about 800 square meters per gram. The activated carbon product may be derived from a renewable feedstock.
