Several industrial unit operations and processes require gas purifications upstream to ensure the required quality of gas being used which in turn would decide the quality of products. Activated carbon is one of the best treatment options for purification and separation of gases. Be it purification of natural gas, compressed gas, reformer gas and specialty gas, or separation of gaseous mixtures, granular activated carbon and activated carbon pellets are can be used in versatile ways to suit different configurations of adsorption systems such as packed bed or fluidized bed columns, pressure/temperature/vacuum swing adsorption, etc.

Owing to its high surface area and superior adsorption/desorption characteristics, activated carbon is also used for gaseous storage to pack large volumes of gas in smaller containers at relatively low pressures.
