| titleOfInvention | Process for the recovery of pentavalent vanadium compounds from acid catalyst extracts |
| abstract | ABSTRACT A process for the preparation of pentavalent vanadium compounds by reprocessing acid extracts of vanadium-containing catalysts spent in the hydrotreatment of crude or residual oils, characterized in that extracts containing trivalent and tetra-valent: vanadium are oxidized at a pH between 0.5 and 2.6 with an oxygen-containing gas to form concentrates of tetravalent vana-dium, after which oxidation is carried out at a pH between 2.6 and 4.0 with an oxygen-containing gas to form concentrates of penta-valent vanadium and in that solid vanadium compounds are subse-quently recovered by separating them from the liquid phase. |
