Abstract:A rapid method based on quantitative 1 H NMR spectroscopy for the accurate estimation of paraffins (P), olefins (O), naphthenes (N), and aromatics (A), i.e., PONA, in extremely light to middle cut naphtha (boiling points ranging from C4/C5 to 130/140 °C and various heart cuts in-between, like C5-60, 60-70, 70-90, 90-140 °C cuts and many more that are being processed for BS-VI gasoline pool) has been developed. The method relies on accurate assignments of various kinds of quaternary-carbons, CHs, CH 2 s, and CH… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
