Abstract :
A phenomenological model of downdraft gasification under steady state operation is developed based on previously
published values for the reaction kinetics in the reduction zone. The model predicts a product gas with a composition similar
to that found experimentally, although the model over-predicts the methane concentration. The accuracy of the model is
limited by the availability of data on the initial conditions at the top of the reduction zone.
