Biolubricants Based on Vegetable Oils: From Raw Materials to Specific Uses

Dr. Sergio Nogales Delgado (Badajoz, Spain, 1984) is a multidisciplinary researcher. He obtained his degree in Chemistry and PhD (about biomass emissions during combustion and pyrolysis of several agricultural wastes) at the University of Extremadura (Spain). As a researcher, he worked at the Technological and Scientific Research Center of Extremadura, focused on the improvement of quality parameters of minimally processed products. Also, at University of Extremadura, he has carried out different research works about biomass energy, covering different subjects such as combustion, pyrolysis, hydrothermal carbonization or biodiesel and biolubricant production, among others. Regarding the latter, biodiesel and biolubricant synthesis through transesterification, with the subsequent characterization, has been an interesting research line for the author. With more than 50 research articles published in international peer-reviewed journals, along with more than 60 research communications in international conferences, he has also participated in book chapters about education sciences and sustainable technologies. In short, his interest in the possible contribution of waste valorization through a wide range of green processes has mainly guided (so far) his 15-year scientific career.

Carmen María Álvez Medina (Táliga, 1993). She obtained her Chemical Engineering degree at University of Extremadura (Spain) in 2022, completing her master degree in Renewable Energies in 2023 at the same university. Currently, she is doing doctorate studies about different energy/material production from biogas and syngas. Having worked for different research projects, her main interests are biodiesel and biolubricant production, biogas steam reforming, Fischer-Tropsch processes or hydrothermal carbonization, among others.

Prof. Dr. Juan Félix González González (Badajoz, Spain, 1961). He is an experienced university professor at the Industrial Engineering School (University of Extremadura, Spain), leading several courses in different university degrees mainly related to Engineering and Renewable Energies. He received his degree in Chemistry and the PhD degree at the University of Extremadura. Also, he takes part in the design and impartation of different master degrees based on renewable energies and sustainability at the same university. With an extensive experience in research (reflected in multiple international works published in peer-review journals), his current research in the Department of Applied Physics is based on combustion, pyrolysis, gasification, thermochemical processes, energy use of biomass waste, active carbons and biodiesel or bioethanol production.
