Exploring fatty acid methyl esters

The search for alternative fuels led to the development of biodiesel research. However, in order for biodiesel to meet the prescribed standards, it must first fulfil the proportion of fatty acid methyl esters (FAME) in its composition. Among several possible methods for the determination of FAME, the standard prescribes the use of gas chromatography (GC). The aim of this study was to provide an overview of the international literature dealing with this topic over the last five years. To achieve this goal, a search of the Web of Science database (WoS) was carried out, followed by a bibliometric analysis in the VOSviewer software. The analysis included 99 studies published over the last five years. The main authors, countries, institutions, journals and keywords were identified to highlight important contributions in the field. The scientific mapping revealed collaborative networks and research focus areas such as analysis, catalysts, conversion, yield, biomass, but also biodiesel production itself. The review showed that this research is carried out by scientists from different scientific categories linked by this highly topical issue in total link strength of 273.
