Magnetic resonance in chemistry : MRCREFERENCES. 58(12)
High-field nuclear magnetic resonance (NMR) has proven to be a valuable tool to analyze petroleum products but has never acquired widespread acceptance in routine work in oil refinery due to the high cost. The advent of compact, reliable, and afforda

In this work, we report the feasibility study to predict the properties of neat crude oil samples from 300-MHz NMR spectral data and partial least squares (PLS) regression models. The study was carried out on 64 crude oil samples obtained from 28 dif

We address the problem of real-time monitoring of products' properties from spectroscopic measurements. Spectra are used as inputs for soft-sensors that estimate outputs difficult to measure on-line. To overcome the issues associated to calibrating s

In the present work, on the basis of a detailed experimental analysis, we propose a mathematical model for the interpretation of the hydrogenation of aromatic compounds during gasoil hydroprocessing. The model considers a lumped scheme for gasoil com
