Quality Monitoring of Biodiesel and Diesel/Biodiesel Blends: A Comparison between Benchtop FT-NIR versus a Portable Miniaturized NIR Spectroscopic Analysis
نویسندگان
چکیده
A methodology such as near-infrared (NIR) spectroscopy, which enables in situ and real-time analysis, is crucial to perform quality control of biodiesel, since it blended into diesel fuel the presence contaminants can hinder its performance. This work aimed compare performance a benchtop Fourier Transform (FT) NIR spectrometer with prototype portable, miniaturized (miniNIR) detect quantify biodiesel diesel. In general, good models based on principal component analysis-linear discriminant analysis (PCA-LDA) FT-NIR spectra were obtained, predicting high accuracies (between 75% 95%), well partial least square (PLS) regression predict concentration diesel/biodiesel blends, coefficients determination 0.83 0.99) low prediction errors. The miniNIR prototype’s PCA-LDA enabled target 66% 86%), PLS model reasonable coefficient (0.68), pointing device’s potential for preliminary which, associated cost portability, could increase control.
