| 摘 要： | 在氧化性气氛中采用固定床反应系统对合山原煤进行了热解脱硫效果考察。主要考察了热解温度、热解时间对煤中挥发分和硫变化的影响。结果发现:随热解温度的升高,挥发分的损失量增加,而半焦的含硫量呈现先是升高而后下降的变化趋势;随热解时间的延长,挥发分的损失量增加,而半焦的含硫量呈现先是下降而后升高的变化趋势。

| Abstract: | The raw Heshan coal was pyrolyzed in a fixed-bed reactor in oxidative atmosphere to examine the sulfur removal efficiency and the volatilization content.The effect of temperature and time on sulfur was studied.The results show that the volatilization content increased and the sulfur content in char increased at the beginning,then decreased with pyrolytic temperature becoming higher;the volatilization content increased and the sulfur content in char increased at the beginning,then decreased with pyrolytic time becoming longer. |
