FIELD: oil and gas industry.
SUBSTANCE: zeolite-containing catalyst is proposed based on high-silica zeolite, which includes hydrogenating components and additives with the following components ratios, wt %: zeolite 50.0-70.0; MoO3 4.0-5.0; ZnO 1.0-3.0; P2O5 1.0-2.0; B2O3 1.0-3.0; γAl2O3 - the other are up to 100. At that, zeolite of ZSM-5 structural type is used as a base, having: crystallinity degree 95-100%; crystallite size 5-30 mcm; static capacity by heptane 0.18-0.21 cm3/g; silica module 30.0-55.0.
EFFECT: increased output of target product, reduction of its chilling point, carrying out dewaxing process at lower temperatures.
