Desarrollo de nanopartículas de magnetita Soportadas en un material micrométrico para remoción y subsecuente descomposición catalítica de crudo emulsionado en aguas de producción
(Universidad Nacional de ColombiaMedellín - Minas - Maestría en Medio Ambiente y DesarrolloDepartamento de Geociencias y Medo AmbienteFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2019-06-01)
En la industria de petróleo y gas se producen grandes cantidades de fluidos que deben ser manejados según su naturaleza y fin. El agua de producción debido a su volumen y composición se ha convertido en uno de los mayores ...
Desarrollo de un proceso de producción fotofermentativa de hidrógeno a partir de suero de leche
(2018-05-17)
El hidrógeno es un gas importante como fuente de energía limpia y como materia prima de algunas industrias. Los procesos biológicos de producción de hidrógeno están ganando importancia debido a las ventajas de sus condiciones ...
Fuels from bio-oils: Bio-oil production from different residual sources, characterization and thermal conditioning
(Elsevier, 2012-05)
Bio-oils from different residual biomass raw materials (pine wood, mesquite wood and wheat shell) were produced by means of conventional pyrolysis at a temperature of 550°C during 60 min. Bio-oils were separated from gases, ...
Hydrogen production from ethylene glycol reforming catalyzed by Ni and Ni–Pt hydrotalcite-derived catalysts
(Elsevier, 2016-12)
In this work, we report a study of the steam reforming (SR) and the aqueous phase reforming (APR) of ethylene glycol (EG) with catalysts based on Ni, prepared from hydrotalcite-like compounds. The Pt–Ni bimetallic catalyst ...
CO2 reutilization for methane production: Via a catalytic process promoted by hydrides
(Royal Society of Chemistry, 2019-09)
CO2 emissions have been continuously increasing during the last half of the century with a relevant impact on the planet and are the main contributor to the greenhouse effect and global warming. The development of new ...
Structures and reactivity of peroxy radicals and dimeric products revealed by online tandem mass spectrometry
(Springer, 2021-01)
Organic peroxy radicals (RO2) play a pivotal role in the degradation of hydrocarbons. Theautoxidation of atmospheric RO2 radicals produces highly oxygenated organic molecules(HOMs), including low-volatility ROOR dimers ...
