  • Process for the demetallization and hydroconversion of heavy crudes and residues using a natural clay catalyst
    Patent number: 4613427
    Abstract: A natural active stable catalyst for use in the hydrodemetallization (HDM) and the hydroconversion (HC) of heavy crudes and residues and, in particular, a method for the preparation of the catalyst from natural clay and a process for the treatment of heavy crudes and residues with the catalyst. The catalyst is free of hydrogenating metals of Groups VIB and VIII of the Periodic Table and comprises primarily iron, silica and alumina derived from the composition of the natural clay. The catalyst possesses a surface area of between 20 to 100 m.sup.2 /g, a total pore volume of between 0.20 to 0.90 cc/g, where 50 to 100% of the total pore volume contains pores of diameter greater than 400 .ANG.. The catalyst has a ratio I(Fe)/I(Si+Al) of between 0.2 to 0.9 as determined by XPS.
    Type: Grant
    Filed: August 28, 1985
    Date of Patent: September 23, 1986
    Assignees: Intevep, S.A., Universidad Central de Venezuela
    Inventors: Gonzalo Sepulveda, Marcos Rosa-Brussin, Nereida Carrion, Pedro Roa, Alfredo Morales Ruiz, Jose Guitian, Otto Rodriguez, Carlos Zerpa
