The relationship between the carbon dioxide content of carbonates in the bomb calorimeter combustion residues and that in the corresponding oil shale samples originated from different deposits was investigated. As a result, a criterion for applying a correction for undecomposed carbonates to gross calorific value was established. A suitable standard method for determination of gross calorific value of oil shale samples was also suggested.
