Abstract
Abstract Gases are stored by combining with a bed of capturing solids at elevated temperatures and pressures. The solids are placed in canisters which are then placed in an autoclave. The gases to be stored are fed directly to the canister via a conduit passing through the autoclave wall.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A method of storing gas by high temperature and pressure absorption, adsorption or reaction with a bed of capturing solids comprising the steps for (a) placing the capturing solids in a relatively thin-walled container having an opening therein connectable to a conduit, (b) placing the thin-walled container in a pressurizable autoclave, (c) bringing the opening in the thin-walled container into communication with a conduit extending through the walls of the autoclave and communicating with the source of gas to be stored, (d) heating and simultaneously pressurizing the autoclave and the interior of the thin-walled vessel by pumping gas to be stored into the thin-walled vessel as gas is absorbed, adsorbed or reacted with the bed of solids, (e) cooling and thereafter depressurizing the autoclave and the thin-walled vessel and its contents, and (f) opening the autoclave, sealing said vessel, disconnecting the conduit from the thin-walled vessel and removing a substantially non-pressurized container loaded with absorbed, adsorbed or reacted gases.
Claim 2
Independent Claim
159 words
A method of storing gas by high temperature and pressure absorption, adsorption or reaction with a bed of capturing solids comprising the steps for (a) placing the capturing solids in a relatively thin-walled container having an opening therein connectable to a conduit, (b) placing the thin-walled container in a pressurizable autoclave, (c) bringing the opening in the thin-walled container into communication with a conduit extending through the walls of the autoclave and communicating with the source of gas to be stored, (d) heating and simultaneously pressurizing the autoclave and the interior of the thin-walled vessel by pumping gas to be stored into the thin-walled vessel as gas is absorbed, adsorbed or reacted with the bed of solids, (e) cooling and thereafter depressurizing the autoclave and the thin-walled vessel and its contents, and (f) opening the autoclave, sealing said vessel, disconnecting the conduit from the thin-walled vessel and removing a substantially non-pressurized container loaded with absorbed, adsorbed or reacted gases.
Claim 3
Independent Claim
152 words
A method of storing radioactive krypton or the like by high temperature and pressure absorption with a bed of capturing zeolites comprising the steps for (a) placing the capturing zeolites in a relatively thin-walled container having an opening therein connectable to a conduit, (b) placing the thin-walled container in a pressurizable autoclave, (c) bringing the opening in the thin-walled container into communication with a conduit extending through the walls of the autoclave and communicating with the source of krypton, (d) heating and simultaneously pressurizing the autoclave and the interior of the thin-walled vessel by pumping krypton to be stored into the thin-walled vessel as gas is absorbed by the bed of zeolite, (e) cooling and thereafter depressurizing the autoclave and the thin-walled vessel and its contents, and (f) opening the autoclave, sealing said vessel, disconnecting the conduit from the thin-walled vessel, and removing a substantially non-pressurized container loaded with absorbed radioactive krypton.
Claim 4
Independent Claim
152 words
A method of storing radioactive krypton or the like by high temperature and pressure absorption with a bed of capturing zeolites comprising the steps for (a) placing the capturing zeolites in a relatively thin-walled container having an opening therein connectable to a conduit, (b) placing the thin-walled container in a pressurizable autoclave, (c) bringing the opening in the thin-walled container into communication with a conduit extending through the walls of the autoclave and communicating with the source of krypton, (d) heating and simultaneously pressurizing the autoclave and the interior of the thin-walled vessel by pumping krypton to be stored into the thin-walled vessel as gas is absorbed by the bed of zeolite, (e) cooling and thereafter depressurizing the autoclave and the thin-walled vessel and its contents, and (f) opening the autoclave, sealing said vessel, disconnecting the conduit from the thin-walled vessel, and removing a substantially non-pressurized container loaded with absorbed radioactive krypton.
Claim 5
Dependent Claim
38 words
A method according to claim 2 wherein in step (d) the contents of the autoclave are heated to a temperature in excess of 500° C. and the pressure in the autoclave is raised to at least 15,000 psi.
