Method for producing graphite from paper

Abstract

The invention relates to a method for producing graphite from paper for use as a filter or construction material. The aim of the invention is to provide a cost-effective, simple and sustainable method for producing graphite. The aim is achieved in that paper / wastepaper, paper shreds or paper strips are soaked in water in a suitable container for several hours; in that the soaked paper is mixed and comminuted using a suitable device until a paste or a mixture having a paste-like consistency forms, wherein sugar or starch is added to the paste as a binder; in that the paste is inserted into a suitable mold, and the water is subsequently pressed out of the paste by pressing or in that the paste is isostatically pressed, so that a pressed product is formed; and in that the dewatered pressed product is removed from the mold and carbonized in a furnace at > 1000°C and then graphitized at > 2000°C (at most up to 3000°C).
