Research Interests
Biodiesel is a renewable fuel source produced via transesterification of fatty acids in plant oils and animal fats. Biodiesel is composed of a series of fatty acid methyl esters (FAMEs) that are characteristic of the feedstock type. Biodiesel can be blended with traditional petro-diesel, a fossil fuel, in any proportion, but typically at a level of 20% or less (B20 or less). The Hupp Lab studies the FAME profiles of various feedstocks using Gas Chromatography with Mass Spectrometry detection (GC-MS). With the rich data provided by GC-MS, we utilize chemometric methods, such as Principal Component Analysis (PCA) and Partial Least Squares (PLS), to further characterize biodiesel feedstock source and concentration.
