(Pergamon-elsevier Science LtdOxfordInglaterra, 2006)
Valorización de biomasa residual mediante procesos pirolíticos y catalíticos
(Universidad Nacional Autónoma de México, 2020)
Se estudia la obtención de productos de alto valor agregado mediante reacciones catalíticas de hidrogenación de biolíquidos obtenidos por pirólisis de residuos de Festuca Alta, de ahora en más festuca. Esta es una gramínea ...
Ethanol and Water Adsorption on Close-Packed 3d, 4d, and 5d Transition-Metal Surfaces: A Density Functional Theory Investigation with van der Waals Correction
(AMER CHEMICAL SOCWASHINGTON, 2012)
Nowadays, there is a great interest in the economic success of direct ethanol fuel cells; however, our atomistic understanding of the designing of stable and low-cost catalysts for the steam reforming of ethanol is still ...
Development of catalytic membranes over PdAu selective films for hydrogen production through the dry reforming of methane
(Elsevier B.V., 2018-07)
PdAu composite membranes were applied in the preparation of catalytic membranes for hydrogen production. The APTES surface modification of PdAu membranes synthesized by sequential electroless deposition was carried out. ...
Valorisation of plant oil derivatives via metathesis reactions: study of the cross-metathesis of methyl oleate with cinnamaldehyde
(Elsevier, 2020-02)
The cross-metathesis of methyl oleate (MO) with cinnamaldehyde (CA) to yield 2-undecenal, methyl 11-oxo-9-undecenoate, methyl 10-phenyl-9-decenoate and 1-decenylbenzene was investigated using the second-generation ...
Síntese de complexos de rutênio (III) derivados de bases de Schiff e análogos e aplicação em catálise da oxidação de alcoóis
(Universidade Federal de Minas GeraisUFMG, 2016-08-04)
In this work we synthesized three bis-imines formed by the condensation between salicylaldehyde and phenylenediamine (ortho and meta) or mphthaldialdehyde and o-aminophenol with yields ranging from 70% to 90%. These bisimines ...
