Patent number: 8357342Abstract: A multiphase multifunctional reactor, system and method is described which has the capacity to effect extractive oxidation of sulfur and nitrogen compounds and unstable unsaturated compounds that are present in raw hydrocarbon streams, in such a way that the reaction conditions are adjusted and avoid losses of yield of the treated hydrocarbon in the stages of the extraction and/or absorption. The objective is achieved by means of the conception of a reactor which comprises a column divided into five sections which can be classified as two reaction sections (1, 2) two decantation sections (3, 4) and an inert gas section (5) under pressure.Type: GrantFiled: September 15, 2009Date of Patent: January 22, 2013Assignee: Petroleo Brasileiro S.A.-PetrobrasInventors: Wladmir Ferraz de Souza, Adriana Moret Borges, Jose Antonio Vidal Vieira

Patent number: 7988924Abstract: The present invention relates to a device and respective process for distribution of mixed charges comprising a flat tray in the form of a disc drained by a series of drainage tubes located above the surface of fixed beds of catalysts, capable of promoting the homogenisation and distribution of charges by means of said device. Such drainage tubes mounted in said manner have the objective of restricting and reorienting the flow of mixed charges, multiplying the points whereon they fall, principally of the liquid phase, onto said beds of catalysts. For the purpose of doing so said drainage ducts, being segments of tubes, distributed on the entire surface of said tray possess caps affixed at the upper extremity thereof impeding the direct flow of charge onto the bed of catalyst, creating a reservoir of liquid on the tray, subsequently being drained down such device in a more controlled manner.Type: GrantFiled: October 10, 2008Date of Patent: August 2, 2011Assignee: Petróleo Brasileiro S.A. - PetrobrasInventors: Wilson Kenzo Huziwara, Donizeti Aurelio Silva Belato, Jose Antonio Vidal Vieira, Angelo Jose Gugelmin, Shelton Rolim Cercal, Jorilvaldo Medeiros, William Victor Carlos Candido, Ademaro Marchiori, Jorge Roberto Duncan Lima, Roberto Ruva, Marcelle Vensão Camargo Foschiani, Alinson Francisco Geros

Patent number: 7972570Abstract: A distributor nozzle for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device includes a number of fixing bars and a deflector cone frustum. The deflector cones or cone frusta may have more than one angle in order to improve the distribution, and they have a number of apertures or slits and a number of vertical directing elements or a directing cage or frame to direct the stream of the two-phase charge in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the entire area of the bed in the reactor.Type: GrantFiled: November 25, 2008Date of Patent: July 5, 2011Assignee: Petróleo Brasileiro S.A.—PetrobasInventors: Jose Antonio Vidal Vieira, Wilson Kenzo Huziwara, Donizeti Aurelio Silva Belato, Ademaro Marchiori, Jorge Roberto Duncan Lima, Fabricio Torres, Carlos Otavio Brito

Publication number: 20080295393Abstract: The invention relates to the field of methods used for the transesterification of oils and fats in order to produce diesel oil. The invention provides a novel method for the production of diesel oil by transesterifying fatty acid esters present in vegetable oils and fats, using a novel catalyst consisting of the oxide of a group V metal and having the formula X2O5, such as niobium pentoxide (Nb2O5). Unlike in the methods used traditionally according to the prior art, the oils are converted here into high-purity products, including glycerol, in yields of the order of 100%, while using significantly less catalyst for a quantity of oil processed, when e.g. soya-bean oil, cotton-seed oil and canola oil are processed by the method according to the invention.Type: ApplicationFiled: May 30, 2008Publication date: December 4, 2008Applicant: PETROLEO BRASILEIRO S.A. - PETROBRASInventors: Marcio de Figueiredo Portilho, Jose Antonio Vidal Vieira, Jose Luiz Zotin, Michele Sabba da Silva Lima
