A catalyst comprising a modified mordenite zeolite catalyst modified with Pt and a promoter selected from the group consisting of Group IIB, Group IVA, Group VIB and mixtures thereof is effectively used in a process for the simultaneous dehydrogenation and isomerization of paraffins to isoparaffins and isoolefins under controlled conditions. The catalyst is prepared by depositing on the modified mordenite zeolite catalyst sequentially Pt and thereafter the promoter.

Catalyst for use in the dehydrogenation and isomerization of paraffins

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.
