Method for producing porous carbon or graphite
A method for producing porous carbon or includes filling pulverised dry or dried wheat or rice starch into a mould/a container (1) as a compact mass (2); compressing/compacting the mass (2) in the mould/the container (1); initiating a shrinkage process by heating the mass (2) in the filled mould/container (1) in a kiln to a first temperature level of 170° C.-450° C. in an oxidising or inert atmosphere; stabilising the heated mass (2) over an extended period of time, then slowly heating the mass (2) further in the kiln in a heating ramp for carbonisation at a second temperature level to >1,000° C. or, for graphitisation, to >2,500° C. under shielding gas to form the most compact blank (5) possible; and removing the compact blank (5) from the mould/the container.
