摘　　要：对烟煤与木质素类生物质松木屑、纤维素类生物质秸秆在固定床反应器中共热解行为进行了系统的实验研究,并对气体产物和焦油组成进行了分析.结果表明,烟煤与两种生物质共热解时存在明显的协同作用,挥发分产率的实验值较计算值有所增加,且使用松木屑时增幅较大.松木屑与烟煤共热解时焦油中愈创木酚类含量显著提高,在400℃松木屑配比为80%时,增量高达25.89%.焦油中酚类含量比计算值高,而PAH和烃类含量则明显降低,同时焦油产生了一定的轻质化.Rapid co-pyrolysis behavior of bituminous coal with two types of biomass,pine sawdust（lignin-rich）and cornstalk（cellulose-rich）was carried out in a fixed bed reactor.The oil and gas products from pyrolysis were subsequently analyzed.The results showed that there was a synergy effect between bituminous coal and two biomass samples during co-pyrolysis process.During co-pyrolysis,the yield of volatile matter increased compared to the calculated values.The most significant change was observed in case of pine sawdust.The concentration of guaiacols in tar from pine sawdust and bituminous coal co-pyrolyssis increased significantly up to 25.89%compared to the calculated values,especially at 400 ℃ and pine sawdust ratio of 80%.The concentration of phenols in co-pyrolysis tars was increased compared to the calculated values,while the concentration of PAH and hydrocarbons was significantly decreased.There seemed to be a shift of oil components towards the smaller molecular weight products.
