摘      要：To predict and analyze the municipal solid waste(MSW)pyrolysis and gasification process in an updraft fixed bed more veritably and appropriately,numerical modeling based on Gibbs energy minimization was executed using the Aspen plus *** RYield module was combined with the RGibbs module to describe the pyrolysis section,while the RGibbs module was used for the gasification section *** proposed model was used to forecast and analyze the target performance parameters including syngas composition,lower heating value(LHV)and carbon conversion rate under different conditions of the gasification temperatures,and ratios and types of gasifying *** results indicate that there is a good agreement between the experimental data and the simulated data obtained using this *** predicted optimum gasification temperature is approximately 750°C,and the best ratio of water vapor as gasifying agent is around *** mixture of flue gas and water vapor has an economical and recycled prospect among four commonly used gasifying agents.
