FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: invention relates to gas and oil refining, petrochemical industries, namely to a method of cleaning hydrocarbon gases from impurities. Proposed method of purifying hydrocarbon gases from impurities in liquid phase is carried out by adsorption on pre-calcined type X zeolite. Before adsorption, hydrocarbon gas is passed through a layer of strongly acidic sulphocationite catalyst KU-2FPP, which is preliminarily subjected to a swelling process, and after adsorption zeolite is regenerated by desorbing gas at high temperature.
EFFECT: invention increases depth of cleaning of hydrocarbon gases from impurities, among which oxygen-containing organic compounds, sulphur compounds, water and iron salts, as well as longer service life of adsorbent.
