Abstract:
New analytical laboratory tools for the qualitative analysis of alternative and renewable solid biofuels were developed. The aim of this study was to develop and validate a new rapid method for quantitative and qualitative analyses of solid biofuels obtained from a thermal treatment process. X-ray fluorescence spectroscopy (XRF) was applied in combination with a multivariate modelling procedure. The C&RT (classification and regression trees) methods were applied to develop and validate the classifier, which allowed for a distinction between the different biomass origins (agrarian biomass, forest biomass and furniture waste) and between the different possible sources of contamination (plastic, fossil fuels and lignin-cellulose after biomass acid hydrolysis). When the solid fuels were correctly identified, the model attempted to predict the concentration of the individual components using partial least squares regression (PLSR) models. Finally, the C&RT classification algorithm was able to predict the origin of biomass sources with a goodness of fit greater than 95%. For predictions of the addition type, the goodness of fit was greater than 91%. The developed methods could rapidly and adequately determine (qualitative analysis) the origin of the biofuels and indicate the possible source of contamination.
