Research on Pyrolysis Mechanism of Huadian Oil Shale

The extraction of shale oil similar to petroleum by pyrolysis of oil shale is of potential value. Based on the solid-phase thermolysis model, the double extrapolated method is applied to analyze the thermogravimetric data of Huadian oil shale. It is found that the essential procedure of Huadian oil shale pyrolysis accords with internal diffusion, which can be described by three-dimensional diffusion model, and of which the activation energy is 194KJ/mol. Combined the gas-solid reaction model with the solid-phase thermolysis model, the dynamics model of oil shale pyrolysis influenced by internal diffusion is established.
