  • Process for catalytic cracking of a hydrocarbon feed with a MFI aluminisilcate composition
    Patent number: 6726834
    Abstract: A process for catalytic cracking of a hydrocarbon feed, includes the steps of providing an initial hydrocarbon fraction; providing a catalyst comprising an aluminosilicate composition having an aluminosilicate composition having an aluminosilicate framework and containing at least one metal other than aluminum incorporated into the aluminosilicate framework; and exposing the hydrocarbon to the catalyst under catalytic cracking conditions so as to provide an upgraded hydrocarbon product.
    Type: Grant
    Filed: March 28, 2001
    Date of Patent: April 27, 2004
    Assignee: Intevep, S.A.
    Inventors: Andrés M. Quesada, Gerardo Vitale-Rojas, José Velásquez, María Nieves Alvarez
