Patent number: 11962044Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.Type: GrantFiled: November 30, 2020Date of Patent: April 16, 2024Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Eliceo Sosa Hernandez, Marco Antonio Dominguez Aguilar, Hongbo Liu, Jorge Luis Alamilla Lopez, Jorge Flores Castillo, Marco Antonio Hernandez Rojo, Ivan Velazquez Ovando, Cesar Mendez Romero, Luis Manuel Quej Ake

Patent number: 11896954Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine.Type: GrantFiled: June 17, 2021Date of Patent: February 13, 2024Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Federico Jesus Jimenez Cruz, Jose Luis Garcia Gutierrez, Jose Francisco Gaspar Silva Sanchez, Liliana Alejandra Astudillo Lopez Lena, Fidencio Hernandez Perez, Alberto Cabrales Torres, Maria Del Carmen Martinez Guerrero, Marco Antonio Dominguez Aguilar, Arturo Trejo Rodriguez, Florentino Rafael Murrieta Guevara
