| Abstract: | Reactivation with sulfur containing compounds of vanadium-titanium oxide catalysts for partial oxidation ofo-xylene is studied. The efficiency depends on the kind and quantity of sulfur additives. Most proper reactivation towardso-xylene is reached with sulfur in concentrations of 0.20 wt.%. |
