ABSTRACT:
A process for the selective separation of alkenes and/or alkynes from gases obtained by cracking of petroleum products comprising: (a) treating said gases containing at least one alkene and/or at least one alkyne with a macroporous strongly acidic cation exchange resin in its hydrogen form to selectively adsorb said at least one alkene and/or said at least one alkyne; and (b) introducing water, oxygen or an acid in vapor form to simultaneously desorb said at least one alkene and/or said at least one alkyne and to form at least one alcohol, aldehyde, oxide or ester.
