Patent number: 5254240Abstract: A tri-elemental catalyst suitable for hydrocracking and hydrogenation of aromatics-containing petroleum hydrocarbon feedstocks such as hydrotreated cracked feedstock, virgin feedstock, vacuum distillate, middle distillate, mixtures thereof, and the like, is disclosed. The catalyst is suitable for hydrodesulfurization as well as hydrodenitrogenation, thus the feedstock can contain sulfur and nitrogen in addition to the aromatic components. Hydrocracking and aromatics hydrogenation of the petroleum hydrocarbon feedstocks is accomplished under a relatively wide range of process conditions using the tri-elemental catalyst that contains a catalytically active metal phase constituted by a Group VI-B element, a Group VIII first transition series element and a Group VIII second transition series element, all supported on a titania-alumina support containing about 5% to about 30% by weight titania in the support.Type: GrantFiled: February 18, 1992Date of Patent: October 19, 1993Assignee: Intevep, S.A.Inventors: Roberto E. Galiasso, Mary Palma, Edilberto Rodriguez, Fernando Gonzalez, Ricardo Prada

Patent number: 4701435Abstract: A method for producing a catalyst for use in the hydrotreatment, hydrodemetallization and hydrocracking of heavy hydrocarbon feedstocks containing high metal levels of vanadium, nickel and sulfur comprises the steps of preparing a carrier from a naturally occurring material consisting essentially of magnesium silicate having a sheet-type structure, iron and nickel wherein the carrier is prepared directly from the above naturally occurring material or, in the alternative, it can be prepared from the naturally occurring material in combination with a catalyst component. In the event the carrier for the catalyst is prepared from the above naturally occurring material without the addition of the catalyst component, the carrier can be impregnated with the catalyst component. The resultant catalyst is particularly useful in the treatment of heavy hydrocarbon feedstocks.Type: GrantFiled: April 7, 1986Date of Patent: October 20, 1987Assignee: Intevep, S.A.Inventors: Juan J.

Patent number: 4591426Abstract: A process for upgrading feedstocks containing not less than about 200 ppm metals, an API gravity of less than about 20.degree., a Conradson Carbon of more than about 8%, by hydroconversion with hydrogen in the presence of a naturally occurring inorganic material as a catalyst. The invention further provides, inter alia, subsequently fractionating the hydroconverted product and solvent deasphalting the distillation bottoms and optionally hydrodesulfurizing atmospheric distillates and the mix of vacuum gas oils and deasphalted oils separately. When a heavy crude of 12.degree. API, 10% Conradson Carbon, 3.2% sulfur and 350 ppm metals is fed to this process, more than 90% (v/v) of a synthetic crude of 25.degree.API, 0.17% sulfur and only 13.8% (v/v) 950.degree. F.+ fraction may be obtained.Type: GrantFiled: March 28, 1983Date of Patent: May 27, 1986Assignee: Intevep, S.A.Inventors: Julio H. Krasuk, Fernando J. Silva, Roberto E. Galiasso, Alfredo Souto

Patent number: 4469587Abstract: A process for upgrading heavy crude comprises the hydroconversion of asphaltenes and resins in the presence of steam and ammonia at high temperatures, followed by deasphalting to eliminate metals and remaining asphaltenes. By way of the process of the present invention, conversion of asphaltenes and resins is accomplished while at the same time insuring a low formation of gases and coke so as to obtain an end product with a high yield of distillates and low metal content. The process is particularly suitable for any type of heavy crude, for example those of the Orinoco zone, which possess a high content of asphaltenes and metals.Type: GrantFiled: September 2, 1983Date of Patent: September 4, 1984Assignee: Intevep, S.A.Inventors: Roberto E.
