Carbon blends for enhanced gas storage

Abstract

Containers for releasing pressurized contents that include adsorbent such as, for example, mixtures of activated carbons from different sources are described herein.

What is claimed is: 
     
         1 . A container for dispensing pressurized contents comprising:
 a container having at least a first compartment;   a blend of activated carbon comprising up to about 40% coal based activated carbon and about 60% nut based activated carbon contained within the first compartment; and   a propellant contained within the first compartment, wherein at least a portion of the propellant is adsorbed onto the blend of activated carbon.   
     
     
         2 . The container of  claim 1 , further comprising a valve for releasing contents of the container. 
     
     
         3 . The container of  claim 2 , further comprising an actuator for opening and closing the valve. 
     
     
         4 . The container of  claim 1 , further comprising a bag for holding a product to be dispensed within the first compartment. 
     
     
         5 . The container of  claim 1 , further comprising a piston in the first compartment. 
     
     
         6 . The container of  claim 5 , wherein a piston is disposed between the blend of activated carbon and the propellant and a valve. 
     
     
         7 . The container of  claim 1 , wherein the nut based activated carbon is coconut based activated carbon. 
     
     
         8 . The container of  claim 1 , wherein the propellant is selected from the group consisting of air, noble gases, carbon dioxide, and combinations thereof. 
     
     
         9 . The container of  claim 1 , wherein the propellant is carbon dioxide. 
     
     
         10 . A method for dispelling contents of a container, the method comprising releasing adsorbed gas from a blend of activated carbon comprising up to about 40% coal based activated carbon and about 60% nut based activated carbon contained within the first compartment.
