Disclosed are methods for producing carbon foam in which using the vitrinite reflectance values of coals are used to form a blended coal precursor having a targeted vitrinite reflectance value. The targeted vitrinite reflectance value can be used to create similar carbon foam products from one production batch to the next.

Known processes for preparing a porous carbonaceous material require lengthy polymerization and washing steps involving solvents or neutralizing agents. The use of high quantities of pore formers leads to a lower carbon yield and higher costs, and use of sulphuric acid leads to sulphur contamination of the final material, but also to corrosion and corrosive by-products and a more complicated handling of the process. In order allows the manufacturing of a porous carbonaceous material with a high pore volume and avoiding the disadvantages of the known methods, a process is provide that comprise the steps of 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 300° C. and 600° C. for at least 15 min so as to obtain a porous carbonaceous material, which is then cooled so as to form the porous carbonaceous material having a modal pore size and a pore volume and a skeleton density.
