摘　　要：分别在氧化性和惰性气氛中,在不同的热解温度下,对合山原煤与秸秆粉末共热解,考察样品在不同条件下的挥发分逸出量和脱硫效果。实验数据研究分析发现:氧化性气氛下随着热解温度的升高,添加秸秆的煤样与原煤挥发分的损失量均为持续增加,添加秸秆后热解半焦产物的含硫量较原煤有所升高;惰性气氛下随热解温度的升高,挥发分的损失量持续增加,热解半焦产物的含硫量总趋势是下降的,在200℃时半焦含硫量呈现出最低值。Respectively in the oxidizing atmosphere and inert atmosphere, in the different pyrolysis temperature, the mixture of raw Heshan coal and straw powder was pyrolyzed together. To examine the sulfur removal efficiency and the volatilization content of sample under different conditions. Through the experimental data analysis： the volatilization content increased and the sulfur content in char increased at the beginning, after adding straw pyrolysis carbocoal product sulfur content of the raw coal was increased; the volatilization content increased and the sulfur content in char increased general trend, at 200 ℃, the sulfur content in char in the lowest value.
