1. Introduction. Oil shale is commonly defined as a fine-grained sedimentary rock containing organic matter that yields substantial amounts of oil and combustible gas upon retorting [1, 2]. In China, oil shale resources total approximately 719.9 billion tons, which is equivalent to 47.6 billion tons shale oil.

· Deposits of oil shale are found around the world and range in geologic age from Precambrian to Tertiary. The term has a long history of use, predating the “shale oil” and “shale gas” revolution of the early twenty-first century in the United States. Oil shale is sometimes applied to “shale-hosted oil ” or “tight oil” formations

· Accordingly, the two exothermic peaks at 360 °C and 485 °C are associated with the burning of kerogen and bitumen contained in oil shales, respectively. The total calorific value of these two peaks is 2.99 MJ/kg and this energy can be used to heat the raw meal materials in a precalciner or rotary kiln.
