H3PO4- and H2SO4- treated niobic acid as heterogeneous catalyst for methyl ester production
(SpringerDordrechtHolanda, 2010)
1-n-Butyl-3-methylimidazolium tetrachloro-indate (BMI center dot InCl(4)) as a media for the synthesis of biodiesel from vegetable oils
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2007)
Support influence on the basicity promotion of lithium-based mixed oxides for transesterification reaction
(Elsevier, 2013-01)
Solid catalysts comprising Li-based oxides were prepared by LiNO3 impregnation onto supports with different acid/base properties (SiO2, MgO, Al2O3 and Mg(Al)O mixed oxide obtained from hydrotalcite). The materials were ...
Insights on the catalytic behaviour of sulfonic acid-functionalized ionic liquids (ILs) in transesterification reactions - voltammetric characterization of sulfonic task-specific ILs with bisulfate anions
(Royal Society of Chemistry, 2021-01)
This work shows for the first time the link between the amount of free sulfuric acid (as detected by cyclic voltammetry) and the activity of sulfonic-acid-functionalized ionic liquids (ILs) as acid catalysts for a ...
Insights in the biocatalyzed hydrolysis, esterification and transesterification of waste cooking oil with a vegetable lipase
(Elsevier Science, 2020-10)
The present contribution investigates the biocatalytic performance of the lipase obtained from the latex of the native plant known as Araujia sericifera (ASL) in the hydrolysis followed by the esterification of released ...
Transesterification of soybean and castor oil with methanol and butanol using heterogeneous basic catalysts to obtain biodiesel
(Pergamon-Elsevier Science Ltd, 2018-09)
This paper focuses on the preparation and characterization of CaO, MgO and ZnO, both bulk and supported on γ-Al2O3 and their catalytic activity in the transesterification of soybean oil and castor oil with methanol and ...
Biodiesel production from Halamphora coffeaeformis microalga oil by supercritical ethanol transesterification
(Elsevier Science Sa, 2019-11)
The marine benthic diatom Halamphora coffeaeformis is a potential feedstock for biodiesel production. Thisspecies shows high growth rates, important triacylglycerol (TAG) contents and grows in seawater makinglarge-scale ...
Potassium-containing hydroxylated hydrotalcite as efficient catalyst for the transesterification of sunflower oil
(Springer, 2018-09)
Different hydrotalcite-based materials were evaluated as heterogeneous catalysts for the transesterification of sunflower oil with methanol. A set of compounds based on magnesia-alumina structures (MgAl hydrotalcites) were ...
