Abstract
An adsorbent for selective removal of nitrile from a hydrocarbon feedstock includes a substantially homogeneous mixture of a cationic nonacidic zeolite and an inorganic oxide matrix, the zeolite having an accessibility index of between about 0.1 to about 0.4, and the adsorbent being capable, when contacted with a hydrocarbon feedstock containing nitrile and containing dienes in an amount of at least about 1.0% by volume, of adsorbing at least about 80% of the nitrile during contact with at least about 200 volumes of the feedstock per volume of adsorbent.
