FIELD: chemistry.
SUBSTANCE: catalyst for isodewaxing hydrocarbon feedstock C10+ for the production of waxy oils or diesel fuels contains 20-60 wt % of the MTT zeolite structure, 1-3 wt % of the MOR zeolite structure, 0.2-0.4 wt % of platinum, the rest is a binder. The catalyst can be further modified with a metal selected from the group: Ca, Mg, Ba, In, Ce. The method for producing waxy oils or diesel fuels is proposed by contacting a mixture of a hydrocarbon feedstock and hydrogen with the said isodewaxing catalyst under the following conditions: a temperature of 250-350°C, a pressure of 2-15 MPa, a volumetric feedstock rate of 0.5-3.0 h-1, the ratio of hydrogen to feedstock is 350-2000 nl/l.
EFFECT: increasing the yield of the target product in the process of isodewaxing hydrocarbon feedstock.
