摘　　要：采用热重分析和色谱、质谱偶联技术,对三种秸秆类生物质与煤混合热解过程中产生的含硫气体进行了在线检测,研究生物质对煤热解析出的COS气体的影响.研究表明:生物质与煤混合热解时,对析出的含硫气体有明显影响.生物质的加入对COS的释放有明显的促进作用,随着生物质比例的增加,促进作用增强.Thermal-gravimetric analysis （TGA）, gas chromatogram （GC） and mass spectrum （MS） method have been used to study the characteristics of sulphide pollutant that released from the co-pyrolysis of biomass and coal blends. The effects of biomass on the sulphide pollutant gas release in coal pyrolysis have been studied. The results show that when the coal is blended with biomass, the quantity of released sulphide pollutant gases is influenced obviously. COS coming out of blends is earlier than that of coal. The COS is increased with more biomass.
