摘要：以杉木屑为原料,在固定床反应器上探讨了热解条件对杉木屑制备木醋液及其性质的影响,结果表明:热解温度是主要影响因素,在热解温度450℃、升温速率10℃/min、氮气流量100 mL/min的热解工艺下,粗木醋液产率可达57.13%,精制醋液产率可达38.20%。杉木屑热解制备得到的木醋液的6类主要化学成分中,酸类和酚类物质为主要成分,约占总含量的2/3,其次是醇类、酮类和醛类,酯类含量较少。热解工艺条件对木醋液的组成和含量有显著影响,热解温度影响酸类、酚类和醇类含量,升温速率影响酸类和醇类含量,氮气流量影响酚类和醇类含量,酮类、醛类和酯类含量基本不受影响。
The pyrolysis of Chinese fir sawdust in fixed bed was investigated.The influence of pyrolysis conditions(such as pyrolysis temperature,heating rate and flow rate of nitrogen)on properties of wood vinegar was discussed.The results showed that pyrolysis temperature was the main factor that effected the preparation and properties of wood vinegar.The yield of wood vinegar and refined wood vinegar were 57.13%and 38.20%under the pyrolysis conditions of pyrolysis temperature 450℃,heating rate 10℃/min and N 2 flow 100 mL/min.Acids and phenols were the primary components in wood vinegar which occupied about 2/3 of total content.Organic component of wood vinegar was obviously effectedby pyrolysis conditions,pyrolysis temperature effected the content of acids,phenols and alcohols,heating rate effected the content of acids and alcohols,the flow rate of nitrogen effected the content of phenols and alcohols,the contents of aldehydes,ketones and esters were almost not effected by conditions.
