Abstract
The present invention relates to a process and device for the accelerated densification of a porous carbonaceous substrate, of the type consisting in decomposing a hydrocarbon substance in the presence of said substrate under high pressure and at high temperature, decomposition being effected inside a closed reactor allowing the elimination of the hydrogen emitted during the reaction as it is produced, the walls of said reactor having the necessary suppleness for the inner volume thereof to be adapted at any instant, under the effect of the pressure applied, to the volume of the liquid phase which it contains, wherein the hydrocarbon substance to be decomposed is chosen from the group comprising pitches, acenaphthylene, phenanthrene or mixtures of these products. The invention also relates to a process for preparing said substance.
