Реферат: Two PtPd-​zeolite catalysts with bimodal pore texture and proton acidity, containing Pt species inaccessible for sulfur deactivation in ZSM-​5 zeolite were developed using the Song concept. The prepared catalysts were used for deep desulfurization (HDS) of straight-​run and secondary diesel fuel with sulfur content up to 2000 ppm. It is apparent that it is reasonable to pursue the both routes of hydrotreating catalyst development. The Pt(Pd)​-​zeolite catalysts demonstrate high efficiency in deep desulfurization of low-​sulfur straight-​run diesel fuel at 280-​320°C. These catalysts may be of interest for one-​stage hydrotreatment of diesel fractions with a sulfur content of 850-​2000 ppm, e.g. those produced from Azerbaijan oils.
