【摘要】 研究了三种不同煤化程度的显微组分对快速热分解的影响以及显微组分的燃烧特性和脱灰前后焦炭的气化反应性。结果表明,煤的镜质组在快速热分解时,其失重率、气体产物、三苯及酚收率均高于丝质组,而着火温度低于丝质组,但气化反应性没有一定规律。更多还原

【Abstract】 The effects of maceral groups of three different rank coals on rapid-rate heating decomposition characterization of maceral chars, gasification reactivity of deminerlized coal chars were studied in this paper. It has been shown that weight loss fraction, recovery ratio of gas product, phenol and benzene series of vitrinite of coals on raid-rate heating decomposition are larger than those of all the fusinite and the ignition temperature is lower than that of fusinite. These isn’t any definite rule of the gasification reactivity of vitrinite and fusinite chars.更多还原
