FIELD: technological processes; chemistry.
SUBSTANCE: high-boiling oil fractions are dewaxed through contact of high boiling oil fractions with catalyst that contains zeolite of ZSM-5 type, catalyst contains 2-10 wt % of decationated form of zeolite of ZSM-5 type and 90-98 wt % of natural zeolite of clinoptilolite-heulandite type that has been previously treated twice with 25% solution of sal ammonia. Catalyst may also be additionally saturated with solution of nickel nitrate provided that nickel content in it is 1.5-2.5 wt %.
EFFECT: waxy diesel fuel from high-boiling oil fractions.
