Analysis of Pyrolysis and Its Kinetics on Biomass Stalk

In order to design and analyze pyrolysis equipment of biomass,pyrolysis experiments of corn stakl and rice straw are conducted by using thermogrametric analyzer.Results of two biomass materials are compared and found to be similar.Derivative thermogravimetry(DTG) curves of samples show that the higher the heating rate,the higher the temperature of DTG peak.DTG peaks shift to air atmosphere but not nitrogen atmosphere under which there is temperature lag.And chemical reaction kinetic parameters of biomass's pyrolysis can be achieved by Coats-Redfern method,which provides theoreticam foundation for further study on pyrolysis of biomass.
