The present invention relates to a method for making porous carbonaceous monolithic structures, the method comprising the steps of: (i) introducing into a mold a precursor material comprising particles comprising a halogenated polymer having a melting point; ( ii) by simultaneously applying to the precursor material at from 10 to 300 bar (when the halogenated polymer is a vinylidene chloride homopolymer) and from 10 to 150 bar (when the halogenated polymer is different from a vinylidene chloride homopolymer) A pressure P in the range of vinylidene chloride homopolymer) and maintaining the precursor material at a temperature T1 (in the range from T1 ,min = 20°C to T1 ,max = Tm - 50°C , where Tm is the melting point of the halogenated polymer), forming a shaped body comprising particle aggregates of the precursor material, and; (iii) optionally cooling, then demoulding the shaped body; ( iv) introducing the shaped body into a furnace, (v) pyrolyzing the halogenated polymer in the furnace until the porous carbonaceous monolithic structure is obtained. |
