Advanced Energy Systems - Coal and Coal/Biomass to Liquids


Investigation of Coal-Biomass Catalytic Gasification Using Experiments, Reaction Kinetics and Computational Fluid Dynamics


Performer: Virginia Polytechnic Institute and State University

Project No: FE0005476


Accomplishments


The research team has pyrolyzed/gasified biomass under different atmospheres and studied coal/poplar mixtures under different pressures and temperatures in the two-inch fluidized bed reactor. The yields were determined gravimetrically by weighing the coal-biomass mixed fuels used in the reactor before and after each experiment before and after each experiment. Preliminary results indicate that there is a component in the poplar wood that may be increasing the projected gasification yield. Work to determine the effect of CO2 on these reactions is ongoing. Under the modeling task, the reaction kinetics and mechanisms have been determined and researchers are ready to progress to the final phase of model investigation.  The MFIX code is being developed for parallel processing of the coal portion of the coal and biomass reaction. The model has been developed and is being validated. Researchers continue to simulate the biomass portion of the reaction.
