| Abstract: | A reactor with entained flow is employed to study the fast pyrolysis characteristics ofpulverized coal.The effects of coal rank, pyrolysis temperature , pyrolysis time and partideheating on the overall weight loss are investigated. The volatile species evolution characteris-tics during fast pyrolysis is also examined. It is concluded that the temperature of the sec-ondary gas is an important factor that influences coal pyrolysis in the reactor and the specificvolatile species yields of different ranks of coal are quite different from each other. |
