Abstract: The flash pyrolysis is an efficient method to produce liquid and gaseous hydrocarbons from coal.This paper reports the flash pyrolysis characteristics of Zalannoer brown coal of Inner Mongolia in H2 and N2 atmospheres. The experiment was carried out in an experimental entrained reactor. The results showed that the yield of gaseous hydrocarbons by flash pyrolysis in H2 atmosphere is 1.5 times larger than that in N2, and the yield of hydrocarbon liquid in H2 is 70% larger than that in N2 at atmospheric pressure; the yield of hydrocarbon liquid in H2 is 5.8 times larger than that in N2 at 6.0 MPa, and the yield of CH4 is 5.5 times larger in H2 than in N2 at same pressure.

摘要： 报道了中国内蒙扎赉诺尔褐煤在H_2和N_2气氛中气流床反应器快速热解的特性.结果表明:在800℃、常压下,煤在氢气氛中快速热解,其气态生成物的产率是氮气氛中的2.5倍,轻质芳烃比在氮气中增加70%;在800℃、6.0MPa压力下,氢气氛中快速热解所获得轻质芳烃的产率是氮气氛中的6.8倍,甲烷是6.5倍.
