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.

**Dr. Sergio Nogales Delgado**（西班牙巴達霍斯，1984年）是一位多學科研究者。他在西班牙埃斯特雷馬杜拉大學獲得化學學位及博士學位（研究主題為多種農業廢棄物在燃燒和熱解過程中的生物質排放）。作為研究者，他曾在埃斯特雷馬杜拉科技與科學研究中心工作，專注於改善最小加工產品的質量參數。此外，他在埃斯特雷馬杜拉大學進行了多項有關生物質能源的研究，涵蓋燃燒、熱解、水熱碳化、生物柴油和生物潤滑劑生產等不同主題。關於後者，通過酯交換反應合成生物柴油和生物潤滑劑，並隨後進行特徵分析，成為作者的一個有趣研究方向。他在國際同行評審期刊上發表了超過50篇研究文章，並在國際會議上發表了超過60篇研究報告，還參與了有關教育科學和可持續技術的書籍章節。總之，他對於通過各種綠色過程實現廢棄物增值的可能貢獻的興趣，主要指導了他15年的科學職業生涯。
