Process for purifying alkane-containing feed streams by contacting them with one or more metal complexes with intra-crystalline channels according to the general formula: Ma [MXbLc]d (OH)e wherein M represents at least one metal from Group 1b, 2a, 2b, 4a, 7b and/or the nm-noble metals of Group 8; M represents at least one metal from Group 6b, 7b and/or 8; X represents an (iso)cyano-, and/or (iso)cyanato- and/or (iso)thiocyano-moiety; L represents a nitroso-, an amino- and/or a halide-moiety, a, b, c, d and e (when OH is present) provide the electroneutrality; and c and e may equal O. Compounds such as magnesium hexacyano cobaltate and zinc hydroxy hexacyano cobaltate can be used advantageously in the purification of methane by selectively adsorbing carbon dioxide present therein.
