The effect from the P2O5 introduction on the activity of Co(Ni)-Mo/Al2O3 catalysts in hydrotreating reactions of petroleum feedstock was examined. As support served γ-Al2O3, prepared from aluminum hydroxide AlOOH powder TH-60 (Sasol), with the following textural characteristics: SBET = 205 m2/g, Vpore = 0.682 cm3/g, Reff = 48 Å. In order to optimize the amount of the modifier the catalyst samples...
