Carbon monoxide-helium complex

The main applications of PSA are to be found in the production of oxygen from air, dehumidification of gases and purification of hydrogen. Other applications include removal of carbon dioxide, recovery of radioactive waste gas, enrichment recovery of rare gases, purification of helium, purification of natural gases, separation of isomers and separation of carbon monoxide. Separation of iso-parafllns from normal paraffins is accomplished by using a shape-selective adsorbent such as a molecular sieve. Separation of carbon monoxide involves chemical adsorption on complex adsorbents. 

The codeposition of lanthanide atoms and carbon monoxide in an oxygen matrix at liquid helium temperatures leads to a series of carbonyl complexes which from an analysis of the infrared spectra have been assigned the formulae R(CO)i-6 (Sheline and Slater, 1975). The ytterbium compounds have distinctly...
