Evolution of gas and shale oil during oil shale kerogen

Oil shale as a kind of alternative fuel resource has attracted the attention of many researchers. Oil shale is usually converted to valuable oil and gas resources through pyrolysis, and residual solid product is called char. Kerogen, the cross-linked organic matter in oil shale, is the significant source of volatiles from oil shale pyrolysis.
