Title:
Gasification kinetics during entrained flow gasification - Part I: Devolatilisation and char deactivation 
Abstract:
The devolatilisation behaviour of solid fuels and the reactivity of the resulting char are important design parameters for entrained flow gasifiers. The volatile yield and devolatilisation rate of two coals are measured in a pressurised high temperature entrained flow reactor at up to 1600 degrees C and 4.0 MPa and in a wire mesh reactor. A pyrolysis model is derived that describes the influences of temperature, pressure, and residence time on devolatilisation.During the entrained flow pyrolysis...    »
