  • Catalyst for use in the dehydrogenation and isomerization of paraffins and method
    Patent number: 5880324
    Abstract: 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.
    Type: Grant
    Filed: June 22, 1998
    Date of Patent: March 9, 1999
    Assignee: Intevep, S.A.
    Inventors: Maria Magdalena de Agudelo, Trino Romero, Jose Guaregua, Marisela Gonzalez
