Abstract
Build-up granulation and compaction granulation methods are generally known for producing granules from porous inorganic material. In order to allow a cost-efficient yet also reproducible production of porous granules having a more pronounced hierarchical pore structure, the invention relates to a method comprising the following steps: (a) supplying a feedstock flow to a reaction zone in which the feedstock is converted to material particles by means of pyrolysis or hydrolysis, (b) depositing the material particles on a deposition surface () forming a soot layer (), (c) thermally hardening the soot layer () to form a porous soot plate (), and (d) comminuting the soot plate () to form porous granules ().
