Experimental Study on the Pyrolysis Characteristics of the Poplar Wood

The thermal gravimetric analysis of poplar was carried out at heating rates of 20°C/min,40°C/min and 60°C/min with the thermogravimetric analyzer,model Q50.The analysis of TG and DTG curves indicates that the pyrolysis process of the poplar is divided into four stages of drying, pyrolysis preheating, pyrolysis and charring.The thermal hysteresis occurs with the heating rates increasing.
