Structures of Coal, Kerogen, and Asphaltenes

Chapter

Abstract

Hypothetical molecular structures of humic coal, sapropelic kerogens, and asphaltenes are described, including how they change with maturity and how they have been refined over the past 75 years with advances in characterization methods. Due to their importance for modeling oil and gas expulsion , Hildebrand solubility theory and results are outlined. The relationship between aromaticity and coke yield is described. A link is made also between the fundamental mechanism of kerogen decomposition and the types of appropriate global chemical kinetic models.
