Abstract
A method of forming an activated carbon or graphite structure is provided by (1) forming, such as extrusion, of a plasticized mixture of: binder selected from cellulose ether and derivative thereof, starch, and mixture thereof; furfuryl alcohol and/or polyfurfuryl alcohol; and carbon, graphite, or a carbon-containing material; and (2) subjecting the formed mixture to a carbon-forming pyrolysis step. The use of furfuryl alcohol allows extrusion at ambient temperatures and provides a 'reactive' solvent that provides carbon upon pyrolysis.
