Abstract

Official abstract text for this publication.

The present invention provides a high surface area porous carbon material and a process for making this material. In particular, the carbon material is derived from biomass and has large mesopore and micropore surfaces that promote improved adsorption of materials and gas storage capabilities.

First claim

Opening claim text (preview).

What is claimed is: 1. An activated carbon adsorbent, wherein the adsorbent comprises a total pore volume from about 1.5 cc/g to about 2.37 cc/g , a surface area of from about 2700 m 2 /g to about 3421 m 2 /g , a particle size of at least 149 microns, a pore volume from about 1.5 cc/g to about 2.00 cc/g for pores with diameters less than about 50 Å, and a pore volume from about 0.8 cc/g to about 1.13 cc/g for pores with diameters ranging from about 20 Å to about 50 Å. 2. The adsorbent of claim 1 , wherein the adsorbent comprises a methane gravimetric storage capacity of greater than about 200 g/kg at a temperature of about 20° C. and a pressure of about 500 psig.
