Patent number: 10300466Abstract: The present invention relates to a process for modifying the physical and chemical properties of Faujasite Y-type zeolites (FAU), mainly used as a base material of catalyst used in the Fluid Catalytic Cracking (FCC) process, for the interest of the oil refining industry, in which the conversion of oil heavy fractions into lighter fractions, with a higher commercial value, is carried out. The process produces a modified Faujasite Y-type zeolite, with lower sodium content, as low as 75%, than that of the starting Faujasite Y-type zeolite. A mesoporous material associated with the modified Faujasite Y-type zeolite has an average pore size ranging from 2 to 100 nm, having a bimodal or multimodal pore size distribution. The proportion of modified Faujasite Y-type zeolite with respect to the meso-porous material associated to the Faujasite Y type Zeolite can be regulated through the process operation conditions.Type: GrantFiled: September 12, 2016Date of Patent: May 28, 2019Assignee: INSTITUTO MEXICANO DEL PETROLEOInventors: Hector Armendariz Herrera, Maria de Lourdes Alejandra Guzman Castillo, Francisco Javier Hernandez Beltran, Patricia Perez Romo, Jaime Sanchez Valente, Jose Marie Maurice Julien Fripiat

Publication number: 20120040822Abstract: The present invention refers to a method for eliminating silicon or silicon compounds that are contained in alumina based materials without destroying such alumina based materials allowing for their reutilization, its main application is being the regeneration of alumina based catalyst contaminated with silicon, which are used in hydro-treating processes in the oil industry for sulfur elimination and silicon removal from process streams. It is important to note that the procedures and/or conventional methods known so far for the elimination and removal of silicon contained in alumina based materials, use inorganic acids or their mixture in a digestion process which modifies the properties of alumina and of any other element contained in the material, thus destroying the alumina and disabling their reutilization.Type: ApplicationFiled: December 9, 2009Publication date: February 16, 2012Applicant: INSTITUTO MEXICANO DEL PETROLEOInventors: Patricia Pérez Romo, José Marie Maurice Julien Fripiat, Luis Miguel Rodríguez Otal, Pedro Martín Vega Merino, María de Lourdes Alejandra Guzmán Castillo, Candido Aguilar Barrera, Héctor Armendáriz Herrera, Francisco Javier Hernández Beltrán
