Abstract:
A method of gas adsorption and desorption, comprising:passing a gas into an adsorbed layer where at least a portion of the gas is absorbed onto absorption media to form an adsorbed gas and removing heat from the adsorption layer through a distance of 2 mm or less into a microchannel heat exchanger layer; wherein the gas directly contacts the adsorption media without first passing through a contactor material; subsequently, heating the adsorption media through a distance of 2 mm or less from the microchannel heat exchanger layer, and desorbing gas; and wherein heat is exchanged between the adsorption layer and the microchannel heat exchanger layer at a rate of at least 0.5 watts per cubic centimeter, measured over a complete cooling and heating cycle where per cubic centimeter is based on volume of an adsorption cell.
