In this study, biodiesel was produced by using a heterogeneous acid catalyst made from
brewer's spent yeast (BSY). BSY was initially activated by phosphoric acid followed by …

In this research, non-edible Kusum oil was used to convert the free fatty acid into its methyl
esters using a silicotungstic acid catalyst. The microwave as a heat source was used to …

This study reports the kinetics of free fatty acids esterification in waste frying oil, based on a
simpler non-conventional pseudo first-order homogeneous reaction mechanism using a …

Methyl oleate, an example of a FAME (fatty acid methyl ester), was produced by oleic acid
(OA) photoesterification with TiO2 and UVA light. Different parameters were evaluated and …

The development of an efficient and green catalyst is a key step for the esterification of free
fatty acid (FFA) in non-edible oil feedstocks. This study introduces a novel acidic deep …

The training of Chemistry teachers in Brazil has been researched for a few decades and
studies point out to training gaps that reverberate in teaching, especially in basic education …

Caffeic acid (CA) is widely found in nature, and has a broad spectrum of biological activities.
However, the low hydrophilicity and lipophilicity of CA limited its application. Dodecyl …

A functionalized catalyst for catalyzed biodiesel production via a heterogeneous route is a
highly focused area to lower the cost of production and mitigate the drawbacks of …

Adding value to agro-industrial residues is becoming increasingly important, satisfying
needs to promote resources' use efficiency and a more sustainable and circular economy …

Biodiesel production from palm oil and alcohol has been carried out using a K 2 O/NbOPO 4
solid acid catalyst. NbOPO 4 catalyst was synthesized through the sol-gel method, followed …
