VOx/c-Al2O3 catalyst for oxidative dehydrogenation of ethane to ethylene: desorption kinetics and catalytic activity
(Elsevier Science, 2013-01)
This study reports ethane oxidative dehydrogenation (ODH) using lattice oxygen. Ethane ODH is studied under an oxygen-free atmosphere employing a 10 wt.% VOx supported on c-Al2O3. TPR and TPO show that the prepared 10 wt.% ...
Al2O3 nanofibers prepared from aluminum Di(sec-butoxide)acetoacetic ester chelate exhibits high surface area and acidity
(Academic Press Inc Elsevier Science, 2021-11)
Alumina (Al2O3) is a widely used material for catalysis in the chemical industry. Besides a high specific surface area, acid sites on Al2O3 play a crucial role in the chemical transformation of adsorbed molecules, which ...

Kinetic study of the ethyl lactate synthesis from triose sugars on Sn/Al 2 O 3 catalysts
(Elsevier Science, 2017-07)
The reaction kinetics of the liquid-phase synthesis of ethyl lactate from dihydroxyacetone and ethanol was studied on Sn-promoted alumina catalysts. Yields of ≈70% were obtained at 353K after 7 hours of reaction. The effect ...
Kinetic and mechanistic study of triose sugar conversion on Lewis and Brønsted acid solids
(Elsevier B.V., 2017-12)
The effect of catalyst acid site nature on the reaction kinetics of the liquid-phase conversion of dihy-droxyacetone with ethanol was investigated using Brønsted and Lewis acid solids. The reaction proceedsthrough a complex ...
Valorización catalítica de triosas: obtención de ésteres del ácido láctico y otros oxigenados valiosos
(2017-06-30)
En esta tesis se investigó la transformación en fase líquida de un compuesto hidroxicarbonílico obtenido durante la conversión de azúcares en las biorefinerías, la dihidroxiacetona (DHA). El objetivo fue convertir DHA en ...
