Deshidrogenación oxidativa de isobutano

Díaz Velásquez, José de Jesús; Rodríguez, Gerardo; Carballo, Luis M. (Universidad Nacional de Colombia - Facultad de Ingeniería, 2001)

La deshidrogenación oxidativa de alcanos es una reacción interesante debido en gran parte a la diferencia de precio entre los aleanos livianos, y sus correspondientes olefinas, su disponibilidad, y el hecho de que son ...

Óxidos de Molibdeno, Tungsteno, Niobio y Tántalo como posibles catalizadores para la licuefacción de Carbón Bituminoso

Riveros, Raúl Alberto (Bogotá - Ciencias - Maestría en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-09-09)

The present work is a compilation of the main characteristics of metallic oxides, highlighting the oxides of transition metals and their acid-base and oxidation-reduction properties. Focused on the oxides of the metals of ...
