The purpose of the present paper has been to get an overview of, evaluate and systematize the existent data on the heat capacity of kukersite oil shale, as well as to find it out whether there is a need for new data. The study has revealed that the respective information is contradictory and that systematized experimental data on the temperature range below the temperatures of the most intensive thermal decomposition of oil shale are lacking. Also, the examination of the relevant public literature indicated that the specific heat capacity of kukersite has been investigated by a number of researchers till the 1970s. Later, the above-mentioned literary material has often been quoted. With the aim of making the existent data on the specific heat capacity of kukersite comparable and understandable, a complete literature review has been performed by us. The literature analysis presented in this paper is based only on original sources.
