混煤的流化床热解动力学研究
STUDY ON THE PYROLYSIS KINETICS OF BLENDED COAL IN THE FLUIDIZED-BED REACTOR
摘要
Abstract
The micro fluidized bed reaction analyzer (MFBRA) was used to research the emission characteristics and the formation kinetics of methane which is released from the different kinds of coal and the coal blended during the process of coal pyrolysis. The result shows that in the same pyrolysis condition,as the volatile content of coal increased,the beginning temperature of the methane to be released decreased, the maximum releasing rate and the total amount of methane increased, the activation energy (E) of its pyrolysis decreased, which means that the higher the volatile content of coal ,the easier to its pyrolysis reaction. Blended coal can change the quality index of the single coal. The quality index of the coal blended as the water content, volatile content and the ash content etc equals to its weighted average of corresponding single coal. But the activation energy (E) of coal blended doesn't equal to the weighted average of corresponding single coal.关键词
