Abstract
Official abstract text for this publication.
The present application is generally directed to gas storage materials such as activated carbon comprising enhanced gas adsorption properties. The gas storage materials find utility in any number of gas storage applications. Methods for making the gas storage materials are also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method of manufacturing a gas storage monolith comprising: polymerizing polymer precursors to obtain a polymer; pyrolyzing the polymer to obtain a pyrolyzed carbon; and compressing the pyrolyzed carbon at a force of 4 Newtons or greater to create a gas storage material, wherein the gas storage material exhibits a gravimetric methane adsorption of at least 0.12 g methane per g carbon as determined using a capacitance manometer pressure gauge. 2 . The method of claim 1 , wherein pyrolyzing the polymer is performed in an inert atmosphere. 3 . The method of claim 1 , further comprising activating the pyrolyzed carbon before compressing. 4 . The method of claim 3 , wherein activating comprises heating in a CO 2 atmosphere. 5 . The method of claim 1 , wherein compressing forms the pyrolyzed carbon into pellets. 6 . The method of claim 5 , wherein the pyrolyzed carbon and a binder are compressed to create the gas storage material. 7 . The method of claim 5 , wherein compressing comprises compressing with a force ranging from 4 Newtons to 8 Newtons. 8 . The method of claim 7 , wherein compressing comprises compressing into a threaded cylindrical mold. 9 . The method of claim 1 , wherein compressing comprises compressing the pyrolyzed carbon with a force ranging from 4 Newtons to 8 Newtons.
