Abstract

The present invention relates to a method for producing a carbon enriched material having a total metal content below 500 ppm and a pH value in the range of from 6.0 to 8.0. The method involves the steps of providing a biobased carbon precursor; subjecting the biobased carbon precursor to heat treatment in an inert atmosphere at one or more temperatures in the range of from 500 to 1500°C, wherein the heat treatment is carried out for a total time of from 0.5 to 10 hours, to obtain a carbon enriched material; providing the carbon enriched material with a carbon-based coating; subjecting the carbon enriched material to a de-mineralization treatment in an atmosphere comprising at least one halogen-containing gas, wherein the demineralization treatment is carried out at one or more temperatures in the range of from 800 to 1500 °C for a time period in the range of from 5 minutes to 10 hours, so as to obtain a carbon enriched material having a total metal content below 500 ppm and a pH in the range of from 6.0 to 8.0; wherein the de-mineralization treatment is carried out after providing the carbon enriched material with a carbon-based coating.
