Abstract:
Calcined CoMo/γ-Al2O3 hydrotreating catalysts were reactivated by a solution of citric acid and triethylene glycol. The reactivated catalysts were tested in HDS of dibenzothiophene and hydrotreating of SRGO. The reactivated catalysts were showed a significant increase in activity compared to calcined. The highest reactivation was observed for the sample reactivated using a solution of citric acid and triethylene glycol. All catalysts were characterized by means of UV-DRS, FTIR, Raman spectroscopy, XRD, XPS, and HTREM. It has been shown that the addition of triethylene glycol increases the proportion of CoMoS phase and the dispersion of sulfide particles.
