ZEOLITE-CONTAINING CATALYST FOR HYDRODEWAXING OF OIL FRACTIONS Russian patent published in 2021 - IPC B01J29/48 B01J27/19 B01J21/02 B01J23/883 

FIELD: catalysts.

SUBSTANCE: invention relates to catalysts for the petroleum refining industry and can be used in manufacture and use of a catalyst for hydrodewaxing of petroleum fractions. Proposed is a zeolite catalyst based on high-silica zeolite, including hydrogenating components and additives, at the following ratios of components, % wt.: zeolite 70.0 to 80.0; MoO₃ 3.0 to 4.0; NiO 3.0 to 4.0; P₂O₅ 1.0 to 2.0; B₂O₃ 0.5 to 2.0; γ-AI₂O₃ - the rest up to 100. ZSM-5 zeolite is used therein as a base, with: a degree of crystallinity of 100%; crystallite sizes of 2 to 8 mcm; a silicate module of 180 to 200.

EFFECT: increased output of the target product and reduced pour point thereof.
