摘要：

A quantitative kinetics model for describing gas yields of supercritical water gasification (SCWG) of coal was established in this paper. The kinetics model contained pyrolysis, liquefaction, steam reforming, methanation and water-gas shift reaction occurred in supercritical water gasification including both homogeneous and heterogeneous reactions. Then, the kinetics model was applied in our previous work to describe the whole process of SCWG of coal in the fluidized bed reactor. Based on the integrated model, the variations of typical reaction rates and reaction components under wide reactor temperature range were numerical investigated, and the characters of chemical fields in the reactor were revealed. The model and numerical results may provide valuable information for better reactor design, scaling up and operation.
