Development of Kinetics and Mathematical Models for High Pressure Gasification of Lignite-Switchgrass Blends
Performer: Georgia Tech Research Corporation
Project No: FE0005339
The objectives of the proposed study are to obtain experimental reactor data and develop kinetic rate expressions for pyrolysis and char gasification for the coal-biomass blends under conditions free from transport limitations, to develop a detailed understanding of the effect of pyrolysis conditions on the porous char structure, to build mathematical models that combine true kinetic rate expressions with transport models for predicting gasification behavior for a broad range of pressures and temperatures, and to investigate the physical and chemical parameters that might lead to synergistic effects in coal-biomass blends gasification.
