Abstract Content

Asphaltenes are a problematic component of crude oil that causes clogging of oil recovery pipelines and fouling of catalysts during crude oil processing. A better knowledge of their structures is imperative for addressing the problems they cause and also for finding potential uses for these compounds. Recent mass spectrometric studies of asphaltenes from around the world have shown that most ionized asphaltenes produce strikingly similar mass spectra upon collision-activated dissociation. However, previous studies of CAD of ionized model compounds have shown little resemblance to CAD of real ionized asphaltenes. We report here results obtained upon examination of new types of model compounds and different types of asphaltenes studied by using several different approaches.
