FIELD: chemistry.
SUBSTANCE: group of inventions relates to adsorbents for purifying hydrocarbons. Disclosed is an adsorbent for purifying hydrocarbon streams, having an aluminium oxide component, a zeolite component with entrance window size of 5-10 E and an additive metal component. The additive metal component is present in amount of 0.0075-0.0135 mol metal in oxide form per 100 g adsorbent. Aluminium oxide is present in amount of 40-90%. The additive metal component is an alkali metal. The adsorbent preferably contains sodium-saturated zeolite Y and aluminium oxide. A method of producing the adsorbent is disclosed.
EFFECT: adsorbent provides high efficiency when removing CO2, H2S and methanol from an ethylene stream.
