Abstract

The effect of organic matter (OM) content and type of mineral matter (MM) on the oil yield at retorting of different natural oil shale samples, those demineralized by acid treatment ones, and the kukersite OM flotation con­centrate mixed with individual minerals has been described basing on the pre­viously published results. The influence of OM content in Estonian kukersite natural samples and their flotation concentrates on the yield of benzene extract after supercritical water conversion and thermo­bituminization in autoclaves, and on evolution of hydrocarbons in source rock analysis (SRA) has been studied experimentally. A comparative study has been carried out by plotting the oil yields versus the according OM contents. The variations in the adsorp­tion capacity of oil on MM and in the oil yield from a unit of OM are charac­terized by the values of intercept and slope of the approximated linear trendlines.
