Abstract
A common feature of oil shale decomposition models is the bitumen intermediate, which is defined to be a soluble, nonvolatile primary product of kerogen decomposition. Despite the large number of studies that have been conducted on oil shale thermal decomposition, there is a scarcity of data on the bitumen intermediate. The problem with the bitumen intermediate is that, while it is often used in oil shale decomposition, it is seldom measured experimentally. The lack of experimental data can lead to deficiencies in understanding the mechanism and kinetics of oil generation. In this chapter some comments on the role of the bitumen intermediate during oil shale decomposition are examined, with emphasis on its temperature dependence under isothermal and nonisothermal conditions. Data are presented to illustrate that significantly greater conversions of kerogen to soluble products can be accomplished by paying attention to the kinetic behavior of the bitumen intermediate, particularly for oil shales that have a large aliphatic carbon component.
