稻壳在250℃/30 min条件下烘焙后，与无烟煤、烟煤和褐煤3种不同煤化程度煤进行不同比例的混合，混合物分别进行热重分析和高温共热解特性研究。结果表明：热重分析中，添加烘焙稻壳有利于提高无烟煤和烟煤的转化率，其提高率低于5%，但是不利于提高褐煤的转化率；高温共热解实验中，随着烘焙稻壳添加比例的提高，无烟煤和烟煤与烘焙稻壳共热解固体产物减少，气体产物增加，而褐煤与烘焙稻壳共热解固体产量增加，气体产量略有下降；烘焙稻壳的添加有利于共热解产气中H2组分的增加和CO2组分的减少，通过改变烘焙稻壳在混合物中的比例可以对共热解气体组分进行调节。

Rice husk was torrefied at the condition of 250 ℃/30 min,then blended it with anthracite, bituminous coal and lignite at different ratios,which had different coalification degrees. The mixtures were analyzed by Thermal Gravimetric Analyzer (TGA) and co-pyrolysis experiments. The results showed that torrefied rice husk had the advantage of raising conversion of the anthracite and bituminous coal by analyzing the TG curves,the increased rates were no more than 5%,but the torrefied rice husk had a negative effect on the conversion of lignite. In the experiments of co-pyrolysis,with the increase of torrefied rice husk in anthracite and bituminous coal,the solid products of the mixtures were lowered and the the gaseous products were increased,but the torrefied rice husk had an inhibitive effect on lignite. The addition of torrefied rice husk in the blends had the effect of accruing the content of H2 and reducing the content of CO2. So changing the percentage of torrefied rice husk in the mixtures had the effect of regulating the component of syngas.
