Abstract
The composition of the products of cracking of oil shale (OS) from the Kashpirskoe deposit and kerogen isolated from it has been studied. The influence of OS mineral components on the material balance and qualitative composition of cracking products was shown. It was found that the amount of gaseous and solid products in kerogen cracking products decreased, and the yield of liquid products increased. The removal of mineral components from OS led to an increase in the oil content and a decrease in asphaltenes in liquid cracking products; the resin content changed slightly, and the yield of light fractions increased. The effects of mineral components on the structural-group characteristics of resins and asphaltenes in liquid cracking products were determined. The absence of mineral components led to an enlargement of resin molecules; on the contrary, asphaltene molecules became more compact.
