19 Claims

1. A process for the preparation of a porous carbonaceous material comprising:

a) providing at least one carbon source and at least one amphiphilic species,

b) combining at least the carbon source and the amphiphilic species to obtain a precursor material,

c) heating the precursor material to a temperature in the range between 350° C. and 550° C. for at least 15 min so as to obtain the porous carbonaceous material, and

d) cooling the porous carbonaceous material having a modal pore size and a pore volume and a skeleton density

e) comminuting the porous carbonaceous material so as to obtain crushed porous carbonaceous material particles, and

f) heating the crushed porous carbonaceous material particles to a temperature in the range from 700-1500° C.
