Abstract
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.
Claims9
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.
