Characterization and reactivity of organically bound sulfur and nitrogen fossil fuels

Advances in X-ray instrumentation over the last decade have allowed the determination and quantification of organically bound sulfur and nitrogen forms in fossil fuels, which led to deeper understanding of their reactivities. This paper reviews recent technical advances in this area, highlights achievements of significant progress in chemical understanding and areas where further advances will likely occur.
