Abstract RU 2817805 C1

FIELD: chemistry.

SUBSTANCE: invention relates to catalytic chemistry. Disclosed is a method of producing an isodewaxing catalyst, involving the following steps: 1) primary modification of unshaped molecular sieve; 2) secondary modification of the obtained primary modified molecular sieve by impregnation with a modifier; 3) loading of precious metal as an active component on the secondarily modified molecular sieve, its drying and calcination to obtain an isodewaxing catalyst. Also disclosed is an isodewaxing catalyst, a method of producing base lubricating oil, base lubricating oil and an apparatus for producing base lubricating oil.

EFFECT: obtaining base lubricating oil with low cloud point.
