摘要
用内蒙扎赉诺尔褐煤在气流床反应器中进行了快速加氢热解的研究,在500～900℃温度范围及0.1～6.0MPa氢压范围考察了温度、压力等诸因素对热解产物产率的影响.实验结果表明:苯的产率随温度及压力的增加而增加,而甲苯、二甲苯以及苯酚和二甲酚在700～800℃之间出现最高产率.当温度800℃、氢压6.0MPa时,可获轻芳烃液体(三苯+三酚)的最高产率6.62%
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.
