Oil shale is used as fuel for electricity generation and shale oil pro- duction. For power generation, grain size of oil shale has to be 0–25 mm or 0–300 mm of lower heat value Qw = 8.4–8.6 MJ/kg, depending on the mode of production. Grain size for oil production must be in the range 25–125 mm and lower heat value Qw = 11.3–11.6 MJ/kg.
