活性炭
As of 2015 Calgon Carbon sells over 100 product types that use activated carbon, for what the company claims are for "700 distinct applications," including the removal of mercury emissions, air treatment in industrial contexts, purifying soda ash and food liquids like high-fructose corn syrup, removing color and odor, and industrial processes for the chemical and petroleum refining industries. Carbon cloth is used for medical purposes including wound care, various defense applications, and diverse industrial products. Activated carbon can be used in respirators and aids in metal recovery in the mining industry. The company began selling FLUEPAC carbon in 2007, which is powdered activated carbon for filtering the mercury "in flue gas streams from coal-fired electric power plants." In 2014 the company began branching into the ultra-capacitor market, using activated carbon in electric storage cells for hybrid vehicles.
