Abstract:
The current paper presents a study combining experimentation and modelling of char gasification in a continuous fixed bed reactor. The char bed gasification was characterised using the Continuous Fixed Bed Reactor (CFiBR) at CIRAD (Montpellier, France). This reactor replicates the gasification zone apart from the rest of the zones present at fixed bed gasification processes. It is instrumented specifically to allow the measurement of thermal and chemical profiles all the way along the bed. Indeed, measurements for temperature, pressure, gas composition and char conversion rate are performed every 10 cm along the bed. A model of the gasification of wood char in a continuous fixed bed reactor is being developed using COMSOL software. It couples heat and mass transfer phenomena with heterogeneous and homogenous chemical reactions taking place inside the bed.
