FIELD: chemistry.
SUBSTANCE: present invention pertains to adsorption. Description is given of an adsorption method of removing methanol impurities from paraffin hydrocarbons in each phase at low temperature and atmospheric pressure using synthetic zeolite NaA, modified with active metals Ni or Ce, and recycling the adsorbent in a hydrogen stream.
EFFECT: invention shortens duration of the process, reduces power consumption and increases service life of the adsorbent.
