    Abstract: The present invention relates to adsorbents for lower aldehydes which comprises a saturated cyclic secondary amine and a porous carrier therefor.The adsorbent according can eliminate lower aldehydes efficiently at ordinary temperature over a long period and, furthermore, is inexpensive. And the adsorbents, wherein a halogenide of alkali metal or alkaline earth metal is further supported on the porous carrier, have an excellent heat resistance.

    Abstract: A bromine-impregnated activated carbon wherein the contents of any alkali metal, any alkali earth metal and iron are not higher than 0.3 wt % and the content of bromine is not lower than 3 wt %, with respect to the weight of a material activated carbon. The bromine-impregnated activated carbon has improved adsorption characteristics to the alkyl sulfides, which have not been sufficiently removed by activated carbons prepared by the conventional techniques. Further, variations in the absorption characteristics can be reduced and the activated carbon can exhibit a stable performance in removing the alkyl sulfides.
