Abstract
The present invention relates to a process for purifying a syngas of the CO/H2 or N2/H2 type, which consists in removing CO2 and possibly other gaseous impurities (water, etc.) before the gas undergoes a cryogenic process. These impurities are adsorbed by the gas stream to be purified passing over an NaLSX-type zeolite and then desorbed during a regeneration step which may be performed by raising the temperature (TSA) and/or reducing the pressure (PSA or VSA).
