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.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
