Patent ID: 7611566

Claim:
A system for desorption of gas, comprising: a cryogenic gas storage container having an outlet and an inlet; a highly porous gas storage material within said container, said material having an adsorbed gas; a circulation path for gas between said outlet and said inlet, said path comprising: a first path toward a gas consumer; a second path connected with said first path, said second path comprising a recirculation path from said outlet to said inlet; and a heat exchanger connected with at least one of said first and second paths; a pump connected to said second path, said pump selectively pumping gas in said recirculation path toward said inlet; and an auxiliary heater connected to said second path, said auxiliary heater being selected from the group consisting of electric heaters and catalytic heaters; wherein heat supplied by said heat exchanger to gas within said recirculation path results in the gas within said recirculation path being warmed to a predetermined temperature above a cryogenic temperature of said material, wherein the warmed gas within said recirculation path passes into the inlet, circulates through said material, and thereby causes desorption of the adsorbed gas, whereupon the gas from the recirculation path and the desorbed gas exit at the outlet into said recirculation path; and wherein the gas within the recirculation path and the desorbed gas are the same type of gas.
