Abstract

FiberForm^R○ gasification under CO₂ flow is modeled using a recently developed universal solver, KATS-US. The solver uses a single domain approach that resolves oxidation reaction and species transport in both open flow region and porous flow region. The material modeling is based on a set of flow tube experiments, from which the CO₂ test campaign is focused. A novel permeability mixing model is proposed for the properties of decomposing materials, and its effects are studied parametrically. The C-CO₂ reaction is modeled using a two-step oxygen-exchange mechanism that is based on available sites of the carbon. A rate function is proposed for FiberForm^R○, which results in the simulated mass losses matching the experiments.
