Со-Мо/Al2O3 and Ni-W/Al2O3 catalysts were tested in hydrotreating of light cycle oil from catalytic cracking, of the straight-run gasoil, and of their mixture under typical hydrotreating conditions used in industry. The catalysts prepared using PMo12 and PW12 heteropoly acids exhibit high catalytic activity. The Со-Мо/Al2O3 catalyst is more active ...
