In this paper

CO2gasification experiments of typical aquatic plants in Poyang Lake were carried out with the thermo-gravimetric

and the weightless characteristics of Eichhornia crassipes and arundinaceous during gasification were analyzed

and combining with the reaction mechanism models

the gasification reaction kinetics were analyzed. The result sshow that the gasification processes of Eichhornia crassipes and arundinaceous can be divided into drying

preheating

pyrolysis and coke gasification four stages; In the pyrolysis stage

the reaction mechanism of Eichhornia crassipes is closer to the mechanism of Shrink Core Reaction Model

and in the coke gasification stage

the reaction mechanism is closer to be Homogeneous Reaction Model

but the reaction mechanism of arundinaceous is contrary. In the low temperature interval

the reaction activation energy of Eichhornia crassipes and arundinaceous is similar

and in the high temperature interval

the reaction activation energy of Eichhornia crassipes is higher than arundinaceous. Finally

the gasification kinetics equations of Eichhornia crassipes and arundinaceous were given.
