Abstract: Temperature is one of the main factors affecting coal pyrolysis characteristics. The CPD model was adopted to predict the pyrolysis products distribution in this study. Calculations show that the CPD model was practicable and the yield of each product generated during the primary pyrolysis process could be assessed by the proximate and ulti- mate parameters of coal. Research on the influence of temperature (from 500 ℃ to 1 000 ℃ ) on the pyrolysis charac- teristics of typical domestic bituminite and lignite was conducted through a fixed bed pyrolysis furnace with rapid heat- ing. Results indicated that the higher the terminal pyrolysis temperature,the higher yield of the gaseous product while the less solid product remained. After being pyrolysed at 500 ℃ and 1 000 ℃ ,the leached volatile of Shenhua bitumi- nite and Baorixile lignite increased by 301. 48 mL / g and 347. 82 mL / g respectively,and the weight loss ratio of solid specimens increased by 12. 49% and 15. 35% . Due to the different engendering mechanisms,the yield of H2 ,CH4 and CO in gaseous product increased with the rise of pyrolysis temperature,while CO2 decreased.
