Publication number: 20240141239Abstract: The present disclosure involves application of heterogeneous hydrogen donors (DHH) or solid hydrogen transfer agents (SHTA) prepared from a polymer with units containing the structure of naphthalene, phenanthrene or anthracene, which can be supported, anchored or in physical mixture with metal oxides such as alumina, silica, titania or kaolin and/or mixture of them, to be used in beds combined with an ULSD or non-ULSD HDS catalyst, to obtain ultra-low sulfur diesel in cuts and/or streams derived from petroleum and/or a mixture thereof, such as SRGO, kerosine, jet fuel, naphtha, etc. The SHTA of the present disclosure provide an additional amount of hydrogen atoms facilitating the removal of refractory sulfur compounds in the HDS process.Type: ApplicationFiled: October 31, 2023Publication date: May 2, 2024Inventors: Laura Olivia Alemán Vázquez, Fernando Alonso Martínez, Flavio Américo Lagos Galván, María del Rosario Socorro Luna Ramírez, León Pablo Torres Mancera, GRodolfo Aguilar Escalante, Jorge Ancheyta Juárez

Patent number: 9969945Abstract: The present invention relates to a process for the partial upgrading of properties of heavy and/or extra-heavy crude oil by low severity catalytic hydrotreatment in only one reaction step. The process of the present invention is obtained upgraded oil with properties required for its transportation from offshore platforms either to maritime terminal or to refining centers. The process reduces the viscosity of heavy and/or extra-heavy crude oil, and decreases the concentration of impurities, such as sulfur, nitrogen, and metals, in such a way that heavy and/or extra-heavy crude oils can be transported to maritime terminals or to refining centers. The process increases the lifetime of the catalyst and decreased operating costs by reducing consumption of utilities because the operation of the process is carried out at lower severity. The partially upgraded oils obtained in this process can be transported directly to the maritime terminals or to existing refineries.Type: GrantFiled: July 15, 2015Date of Patent: May 15, 2018Assignee: Instituto Mexicano Del PetroleoInventors: Jorge Ancheyta Juarez, Luis Carlos Castaneda Lopez, Jose Antonio D.

Patent number: 9920264Abstract: A process for hydroconversion-distillation of heavy and/or extra-heavy crude oils, which comprises four stages: 1) desalting and separation of the feedstock; 2) catalytic hydrotreating of light fraction (optional); 3) catalytic hydroconversion of heavy fraction, and 4) distillation of hydrotreated products to provide products that can be processed in conventional refining schemes designed to operate with light and intermediate crude oils.Type: GrantFiled: August 30, 2012Date of Patent: March 20, 2018Assignee: Instituto Mexicano del PetroleoInventors: Jorge Ancheyta Juarez, Jose Antonio Domingo Muñoz Moya, Luis Carlos Castañeda Lopez, Sergio Ramirez Amador, Gustavo Jesus Marroquin Sanchez, Guillermo Centeno Nolasco, Fernando Alonso Martinez, Rodolfo Antonio Aguilar Escalante

Patent number: 8431018Abstract: A supported carbon having high surface area, high pore volume containing (i) molybdenum (ii) a metal of non noble Group VIII, (iii) phosphorous, is used for hydrometallization of heavy crude oil and residue. The catalyst contains about 6 to 15 wt % molybdenum as MoO3, about 1 to 6 wt % cobalt or nickel as CoO or NiO and phosphorus as phosphorous oxide. One characteristic of the catalyst is the portion of pores having pore diameter in the range of 200 to 2000 Angstrom of 20 percent or more. The catalyst prepared by chelating agent has higher hydrodesulfurization activity assuming that more dispersed active metals are present on this catalyst. Long run activity studies show that catalyst having only molybdenum supported on activated carbon has good stability with time-on-stream and very high metal retention capacity.Type: GrantFiled: March 3, 2010Date of Patent: April 30, 2013Assignees: Instituto Mexicano del Petroleo, Toyo Engineering CorporationInventors: Samir Kumar Maity, Jorge Ancheyta Juárez, Fernando Alonso Martínez, Hidetsugu Fukuyama, Satoshi Terai, Masayuki Uchida

Publication number: 20110218097Abstract: A catalyst for hydrotreating, especially hydrodesulfurization, of residua and heavy crudes is prepared by synthesizing the support from titanium and boehmite, to form either a titanium/alumina support (TiO2/Al2O3) or a titanium-alumina support (TiO2—Al2O3) that is thereafter provided with at least one hydrogenating metal from group VIB in oxide form and a promoter from group VIII also in oxide form. The (TiO2/Al2O3) support is prepared from boehmite, which is peptized by using an inorganic acid, then extruded, calcined and impregnated with a solution containing titanium, while the (TiO2—Al2O3) support is prepared by admixing boehmite with a titanium-containing solution, peptized using an inorganic acid, extruded and calcined to obtain the titanium-alumina support.Type: ApplicationFiled: May 13, 2011Publication date: September 8, 2011Applicant: INSTITUTO MEXICANO DEL PETROLEOInventors: Patricia Rayo Mayoral, Jorge Ancheyta Juárez, Jorge Fernando Ramírez Solis, Samir Kumar Maity, Mohan Singh Rana, Fernando Alonso Martínez

Publication number: 20070187294Abstract: Two-stage low pressure catalytic hydrotreatment of heavy petroleum hydrocarbons having a high content of contaminants (metals and asphaltenes), is conducted under operating conditions with low-pressure, in a fixed bed or ebullated bed reactor to limit the formation of sediments and sludge in the product and obtain a hydrotreated hydrocarbon of improved properties, with levels of contaminants, API gravity and distillates within the ranges commonly reported in the feedstocks typical to refining schemes. A hydrotreatment catalyst, whose principal effect is the hydrodemetallization and the hydrocracking of asphaltenes of the heavy hydrocarbons of petroleum is used in the first stage, and the second reaction stage employs a hydrotreatment catalyst for a deeper effect of hydrodesulfurization of the heavy petroleum hydrocarbon whose content of total sulfur is reduced to a level required for its treatment in the conventional refining process or for its sale as a hydrocarbon of petroleum with improved properties.Type: ApplicationFiled: July 9, 2003Publication date: August 16, 2007Inventors: Jorge Ancheyta Juarez, Gerardo Betancourt Rivera, Gustavo Marroquin Sanchez, Guillermo Centeno Nolasco, Jose Antonio Domingo Munoz Maya, Fernando Alonso Martinez
