Noble metal hydrogenation catalysts and aromatic saturation methods

Номер: CA3029555C

Disclosed herein are a variety of systems and methods for forming a lubricant boiling range product, including exposing a 600 F+ (316 C+) portion of a hydrocracked effluent to a supported catalyst under effective hydrogenation conditions to form a hydrogenated effluent. The supported catalyst includes 0.1 wt% to 5.0 wt% of a Group VIII noble metal and 0.3 wt% to 2.5 wt% alumina deposited on the silica support, the supported catalyst having a ratio of aluminum atoms in tetrahedral sites to octahedral sites of at least 1Ø The method further includes dewaxing the hydrogenated effluent under catalytic dewaxing conditions to form a dewaxed effluent and hydrofinishing at least a portion of the dewaxed effluent under hydrofinishing conditions to form a hydrofinished effluent comprising a lubricant boiling range product.

Catalytic formulation for producing propylene cyclic carbonate from carbon dioxide using a potassium iodide catalyst

Номер: US11504701B2
Принадлежит: INSTITUTO MEXICANO DEL PETROLEO

This invention is related to the synthesis of organic carbonates from carbon dioxide and epoxides. It is particularly focused on the production of propylene cyclic carbonate from propylene oxide. The proposed catalytic materials includes a support made of aluminum oxyhydroxide (Catapal B®), nitric acid, acetic acid and/or phosphoric acid. An important stage is the physical and chemical conditioning of the catalytic materials and to this end, experimental methodologies such as spheronization and thermal treatments were implemented prior the evaluation process.

Optimizacion del hidrociclon.

Номер: MX2024001661A
Принадлежит: Vulco SA

Controlar el funcionamiento de un hidrociclón para mantener el hidrociclón en un estado de funcionamiento deseado a medida que separa un fluido bombeado en una corriente de rebose y se describe una corriente de descarga inferior. El método comprende medir las vibraciones del hidrociclón a una frecuencia seleccionada dentro de un intervalo de frecuencia predeterminado; comparar una característica de las vibraciones medidas a la frecuencia seleccionada con una pluralidad de valores que representan transiciones entre diferentes estados de funcionamiento del hidrociclón para identificar un estado de funcionamiento actual del hidrociclón; y generar una configuración de ajuste para cambiar el estado de funcionamiento actual identificado al estado de funcionamiento deseado, donde la configuración de ajuste aumenta o disminuye un parámetro de fluido bombeado.

Sistema combinado de absorcion de dioxido de carbono basado en mezclas de liquidos ionicos y aminoacidos.

Номер: MX2016015269A
Принадлежит: Mexicano Inst Petrol

La presente invención describe un sistema absorbente líquido combinado para la captura de CO2 gaseoso. Dicha combinación está dada por la mezcla de un líquido iónico y una solución acuosa de aminoácido. Esta mezcla tiene una absorción mejorada de CO2 respecto a los componentes que la forman por separado y dichos componentes pueden ser regenerados y reutilizados en varios ciclos de absorción sin pérdida de su capacidad absorbente.
