摘要

This study explores the thermal and analytical characterization techniques used for biofuels and their blends, emphasizing the critical role of renewable energy sources in mitigating environmental challenges. This research provides an overview of different types of biofuels, their production methods, and their potential as sustainable energy alternatives. The bibliography study covers research articles, reviews, and conference proceedings published between 2015 and 2024. This study highlights the application of thermal analysis techniques: differential scanning calorimetry (DSC) and thermogravimetry (TG), to evaluate various fuels' thermal stability and degradation. This work discusses analytical characterization methods: gas chromatography–mass spectrometry (GC–MS), Fourier transform infrared (FT-IR), and Raman and nuclear magnetic resonance (NMR) spectroscopies used in assessing the composition and properties of biofuels and their blends. The study introduces advanced characterization techniques: flash DSC, ultraviolet DSC, thermal optical analysis (TOA), and hot-stage microscopy, for analysing the composition and properties of biofuels. There are limited studies with these advanced techniques and hence the need for their use in biofuel analysis. Flash DSC offers faster heating and cooling rates, detecting rapid thermal events up to 40,000 °C per second. Ultraviolet (UV) DSC integrates UV light exposure with thermal analysis, enabling the determination of photostability, photooxidation, and other UV-induced processes in biofuels. TOA determines the carbon content and particulate matter produced during combustion. Hot-stage microscopy will generate visual data, crucial for understanding intricate thermal behaviours and interactions within biofuels. Also, future research should focus on the characterization of biojet fuels using thermal and analytical techniques.
