摘要：In the pressurized rapid pyrolysis process, the two kinds of carbonaceous materials (coal and petroleum coke) presented some different pyrolysis behaviors, resulting in some different effects of pyrolysis conditions (thermal history and pyrolysis pressure) on their physical properties (carbon crystalline structure and surface area). The gasification activity of their resultant chars prepared at the ambient pressure was higher than that of their corresponding ones prepared at the pressurized pyrolysis. However, at the pressurized pyrolysis, the effects of pyrolysis pressure on the gasification activity of their resultant chars were obviously discriminated, which was likely to be quite pertinent with that whether the tars were produced or not during the pyrolysis.
