Abstract :
Isothermal pyrolysis of biomass such as rice straw, pelletized corncob and pelletized corn straw are studied with the furnace temperature of 700degC, 800degC, 900degC by macro-thermal gravimetric(macro-TG) apparatus. The results indicated that biomass type, particle size, ash contents are influential in biomass isothermal pyrolysis characteristics, larger particle size made inadequate pyrolysis of char and longer residence time inhibited char yield, high ash contents conduce high char production. Pyrolysis reaction time can be significantly reduced by rising the pyrolysis temperature. However, it is more fast and more gas/liquid productions in a higher temperature condition.
