FIELD: technological processes.
SUBSTANCE: invention relates to a method of purifying hydrocarbon feedstock containing olefins and at least one impurity, containing at least one heteroatom, involving a step of contacting feedstock with an adsorbent containing 93 wt% to 99.8 wt% zeolite and from 0.2 to 7 wt% binder, wherein zeolite relates to type 12MR, wherein said zeolite contains silicon and an element T, selected from a group consisting of aluminium, boron, gallium and iron, and atomic ratio Si/T in zeolite is less than 20.
EFFECT: used adsorbent has low chemical activity, which does not lead to reduction of capacity for adsorbing impurities.
