Abstract
A carbonaceous molecular sieve having micropores with diameters in the range of 4 to 6 Angstrom units and bromine as adsorbed on said carbonaceous molecular sieve is able to remove selectively low molecular weight organic gases such as ethylene, acetylene, methyl sulfide, acetaldehyde etc. from air and other gases containing the same with a reduced tendency toward deactivation with time, and is useful as a removing agent of low molecular weight organic gases.
