摘要 | In the present work, a revised equilibrium model (gas-solid) was built. The temperature approach to equilibrium for the methane cracking reaction was specified to improve the prediction accuracy. The model was applied and validated in pilot scale experiments using a 150kgh(-1) two-stage downdraft gasifier and a gasifier from the Energy Research Centre of the Netherlands (ECN). The type of gasification agent is a dominant factor that determines product gas composition, quality, and end-use. A theoretical analysis of the effect of gasifying agent on product gas quality and process efficiency was executed based on the model calculation. The optimal operation conditions were established for the three (air, steam, oxygen-steam) gasification processes. For air gasification, an optimal value of equivalence ratio (ER) of 0.31 corresponds to the maximum gasification efficiency. The optimal range of steam/carbon ratio (SR) is between 0.7 and 0.8 for the equilibrium of the water-gas shift and steam reforming reactions. For autothermal oxygen-steam gasification, the H-2 concentration reaches the highest value for SR=1.0. |
