焦油模型物与木屑共热解产物分布规律研究
Study on the distribution law of co-pyrolysis products of tar models and sawdust
摘要
Abstract
In this study,toluene and acetic acid were investigated as model biomass tars,and sawdust was used as the feedstock.Co-pyrolysis experiments were conducted in a first-order fixed-bed reaction system to maximize the tar removal from sawdust.The distribution of co-pyrolysis products at different temperatures and the synergistic effects among the products were discussed.The results showed that compared to the pyrolysis of sawdust alone,the co-pyrolysis of sawdust with toluene and acetic acid ex-hibited a superior tar removal effect.Specifically,the co-pyrolysis of sawdust and toluene effectively reduced the tar yield by 81.47%.From the perspective of tar components,oxygen-containing com-pounds could not be effectively removed during the co-pyrolysis process,while aromatic hydrocarbons were easy to be removed by high-temperature co-pyrolysis.The synergistic effect of co-pyrolysis of acetic acid and sawdust was slightly weaker than that of toluene.The yield change of co-pyrolysis prod-ucts affected by temperature was consistent with that of sawdust pyrolysis alone.Furthermore,the inhib-itory effect of pyrolysis temperature on coke and tar was enhanced,providing a reference for tar removal and efficient conversion.关键词
