Research of pyrolysis and its kinetics on biomass shell type

The studies on three kinds of biomass(walnut shells,peanut shells and shell seeds) were obtained using TG and DTG curves at different heating rates.Kinetic parameters of three biomass were calculated at different heating rates and atmosphere with the method of Coats-Redfern.The results showed that the main pyrolysis process can be described by first order reaction model with the method of Coats-Redfern.
