Particulate carbon materials and method for the separation thereof

A particulate carbon material having a homogeneous distribution of primary particles wherein a ratio of a measured statistical thickness surface area (STSA) to a calculated statistical thickness surface area (STSA) is between 0.7 and 1.3.

A particulate carbon material of a first fraction having a homogeneous distribution of primary particles being obtainable by a process for separating a starting particulate carbon material, the starting particulate carbon material having been obtained by hydrothermal carbonization or precipitation of an organic feedstock, the process comprising conducting gravity separation of the starting particulate carbon material to form at least two fractions including the first fraction and a second fraction,

• wherein the starting particulate carbon material has a starting statistical thickness surface area (STSA) of at least 5 m2/g, the particulate carbon material of the first fraction has a first statistical thickness surface area (STSA) that is at least 5% greater than the starting STSA of the starting particulate carbon material, and the second fraction has a second statistical thickness surface area (STSA) that is smaller than the starting STSA of the starting particulate carbon material.
