Description
Summary:Reaction mechanism takes place in char gasification was tested by kinetic studies. A modified kinetic model (thin reaction zone model) was developed to evaluate the mechanisms controlling the process of gasification. The model was compared to the experimental data of char gasification using steam as gasification agent. The gasification was carried out at 600– 800 ∘ C for 60 min. The model assuming the mass transfer of steam through the ash layer controls the reaction rate work well. The average error at operating temperatures of 600, 700, and 800 ∘ C was 2.89, 1.75, and 3.26% respectively.
