Zeolitic molecular sieves having high SiO2/Al2O3 molar ratios and containing Cucations are found to exhibit a high degree of selectivity and affinity for CO molecules and are capable of separating CO from gas streams even when water vapor is present.
Process for removing carbon monoxide from a gas stream comprising at least 10 ppm CO by volume and at least one other constituent selected from the group consisting of H2O and CO2 which process comprises passing said gas stream at a temperature of from 0 to 300°C. through an adsorbent mass of a crystalline zeolitic molecular sieve having a framework SiO2/Al2O3 molar ratio of from 20 to 200 and having as zeolite constituents monovalent copper cations, whereby CO molecules are adsorbed and a CO-depleted effluent gas stream is obtAined.
