Síntesis y caracterización de membranas compuestas de zeolitas para la purificación de hidrógeno
(2017-03-31)
Para la obtención de la zeolita NaA se estudiaron dos rutas de síntesis: gel concentrado y solución clara. Se determinaron las mejores condiciones para la obtención de de la fase NaA pura y se investigó la influencia de ...
Gas Adsorption Modelling of the Oxidative Coupling of Methane (OCM) Process on Zeolite X Molecular Sieves
(Universidad Nacional de Colombia - Sede Bogotá, 2019)
In this work was studied the modeling of the adsorption of effluent gases from the methane oxidative coupling process (OCM) on CaX zeolite for the separation of ethylene. To describe the adsorption process, a mathematical ...
OXIDACIÓN AVANZADA CON UN REACTOR FOTOCATALÍTICO DE MEMBRANA PARA LA DEGRADACIÓN DEL COLORANTE TIPO AZO RB5
(2011-01-05)
Effluents from industries and home have toxicological compounds which cannot be degraded
at ambient conditions and are wasted to the drainage.
the quality control for the effluents establish parameters to know its pollutant ...
Estimating models for predicting effective permeability of mixed matrix membranes
(Elsevier Science, 2006-06)
Mixed matrix membranes have become a highly potential unique materials in many engineering application to overcome limitations presented by other products. In this contribution, an improved form of Maxwell's equation (the ...
Desenvolvimento de fibras compósitas ultrafinas de policaprolactona, pectina e zeólita faujasita para acondicionamento de cloxacilina
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2020-03-27)
Bovine mastitis and hoof diseases are infections responsible for great economic losses in the Brazilian agricultural sector. Such losses are associated with a reduction in milk and meat production leading to extreme cases ...
Evaluation of heavy crude oil from a water-oil model system as starting material for the preparation of adsorbents type NaY zeolite-templated carbon
(2017-07-01)
In this work, NaY zeolite is explored as a possible “template” to obtain porous materials type ZTC from
the adsorption of heavy crude oil in a water-oil model system (emulsion). In order to produce the adsorbents,
a ...
Hydrogen recovery from the purge stream of an HDA process using the concept of Mass Exchange Networks
(Elsevier, 2013-04)
In this paper we use the concept of Mass Exchange Networks to design the hydrogen recovery from the purge stream of an HDA Process by implementing a recently proposed counter current gas permeation equipment to exchange ...
