Abstract
A known method for producing a porous carbon product comprises producing a monolithic template from inorganic matrix material having pores connected to each other, infiltrating the pores of the template with carbon or a carbon precursor substance forming a green body framework containing carbon surrounded by matrix material and calcining the green body framework forming the porous carbon product. In order to provide a method proceeding herefrom which permits cost-effective production of a product from porous carbon, according to the invention the production of the template comprises a soot separation process in which a hydrolyzable or oxidable starting compound of the matrix material is supplied to a reaction zone, therein converted to matrix material particles by hydrolysis or pyrolysis, the matrix material particles are agglomerated or aggregated and formed to the template.
