Study on co-pyrolysis behavior of Shengli lignite and cron staw

摘要

The co-pyrolysis performance of coal and biomass was studied and the influences of corn straw on Shengli lignite pyrolysis were discussed in this paper. The results show that corn straw has much higher activity and lower char yield than Shengli lignite during pyrolysis process. Release of moisture in blends were more occur than individual pyrolysis of Shengli lignite and corn straw. Weight loss of experimental value was lower than that of calculated value in blends. The pyrolysis process of Shengli lignite was remarkably affected by adding corn straw. There exists positive synergistic effect between Shengli lignite and corn straw in co-pyrolysis process. Corn straw could reduce the pyrolysis activation energy of SL dramatically above 350 oC.
