Abstract: The pressurized fast pyrolysis of Jincheng anthracite was studied in a thermogravimetric fixed-bed reactor. Combined with the thermogravimetric analysis of coal chars gasification by TGS-2, the influence of pyrolysis temperature, residence time and pyrolysis pressure on the characteristics of residual were investigated. The results show that the char yield, the gasification activity, as well as the activation energy are greatly affected by the pyrolysis temperature, residence time and pressure. The BET surface area of the char is high under the long residence time and high pressure, and is low at high temperature. There is not close relationship between the BET surface of the char and its gasification rate. The gasification rate in steam is about three times larger than that in CO₂.
