Abstract
A method of filling a canister containing activated carbon having a first temperature with a propellant gas, wherein the method includes (a) providing a volume of liquefied propellant gas at a second temperature and a first elevated pressure that prevents it from evaporating; (b) evacuating the canister to create a vacuum within the canister, thereby cooling the activated carbon to a third temperature lower than the second temperature; (c) injecting the volume of liquefied propellant gas into the canister at a second elevated pressure that prevents it from evaporating; and (d) allowing the liquefied propellant gas to evaporate, consuming energy as evaporation heat, the energy being generated due to the propellant gas being adsorbed by the activated carbon, thereby reducing the heating of the activated carbon.
