Investigation of Coal-Biomass Catalytic Gasification Using Experiments, Reaction Kinetics and Computational Fluid Dynamics
Performer: Virginia Polytechnic Institute and State University
Project No: FE0005476
Program Background and Project Benefits
This work will use experimental reactor data to 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. The impact of this project will be to develop a cost-effective gasification-based CBTL process to produce renewable liquid fuels that will provide diversity of fuel supply and energy security while resulting in lower future capital and operating costs. Specifically, this project will 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 investigate the physical and chemical parameters that might lead to synergistic effects in coal-biomass blends gasification.
