Determination of the Acidity of Waste Cooking Oils by Near Infrared Spectroscopy
(MDPI, 2019)
Waste cooking oils (WCO) recycling companies usually have economic losses for buying WCO not suitable for biodiesel production, e.g., WCO with high free acidity (FA). For this reason, the determination of FA of WCO by ...

Production of Oxygenated Fuel Additives from Residual Glycerine Using Biocatalysts Obtained from Heavy-Metal-Contaminated Jatropha curcas L. Roots
(MDPI, 2019)
This work aims to shed light on the use of two biochars, obtained from the pyrolysis at 550 C of heavy-metal-contaminated Jatropha curcas L. roots, as heterogeneous catalysts for glycerol esterification using residual ...

Valorization of a high-acidity residual oil generated in the waste cooking oils recycling industries
(Consejo Superior de Investigaciones Científicas, CSIC: Instituto de la Grasa, 2019)
A sludge fraction is obtained from the industries which recycle cooking oil and this sludge con-tains a large amount of oil with an extremely high acidity (> 60%). In this work, we propose a scheme for methyl ester production ...

Metal Accumulation by Jatropha curcas L. Adult Plants Grown on Heavy Metal-Contaminated Soil
(MDPI, 2020)
Jatropha curcas has the ability to phytoextract high amounts of heavy metals during its first months just after seeding. Notwithstanding, there is scarce information about metal uptake by adult J. curcas plants. To shed ...
