Abstract

Pyrolysis of Chinese Huadian oil shale using carrier gases N₂ and CO₂ was investigated by TG-FTIR method. The results show that carrier gas does not change weight loss or mechanism of pyrolysis, while decomposition of carbonates in the mineral part can be retarded by CO₂. This regulation was found to be in accordance with kinetic analytical results. The pyrolysis of oil shale in a fixed bed from room temperature to 500 °C at heating rate of 10-20 °C/min was also investigated. Hydrocarbons are the main components in shale oil, and hydrocarbon derivatives concentrate in the number of C₁₆-C₂₃ by CO₂ retorting, the chains being longer than those of hydrocarbons obtained by N₂ retorting.
