ABSTRACT:
The invention concerns a process for converting heavy petroleum residues to hydrogen and to gaseous and distillable hydrocarbons, comprising the association of a step of hydropyrolysis (inside tube 3) with a step of catalytic steam-gasification of the formed coke (outside tube 3), characterized in that the hydropyrolysis step is performed in the presence of a solid supporting a carbon gasification catalyst circulating between the hydropyrolysis zone and the coke steam-gasification zone, said steam-gasification being performed in the absence of oxygen.
The petroleum residue, hydrogen and steam are introduced respectively through lines 5, 6 and 7.
The products are withdrawn through line 10. Heat may be supplied by the radiating tube 4.
