FIELD: mineral industry.
SUBSTANCE: method for preparing a zeolite-containing oligomerization catalyst, including deactivation of the outer surface of a crystalline zeolite of the ZSM-5 type with a Si/Al molar ratio of 80-1070 by treating it with an organosilicon compound at the stage of catalyst molding, followed by calcination, a zeolite-containing oligomerization catalyst obtained by the described method, as well as its use for the oligomerization of butane-butylene, propane-propylene or pentane-amylene fractions.
EFFECT: improved properties of the zeolite-containing oligomerization catalyst, which makes it possible to reduce coke formation and increase the duration of the single-pass run.
