生物质热解油的热解气化实验研究

An experimental study on gasification of bio-oil

采用固定床生物油气化系统对生物油在不同气化温度、停留时间、气化剂等条件下对生物质流化床快速热解油的热解气化特性进行了研究,并对合成气的组成特性进行了分析。研究发现随着热解气化温度的升高,合成气中CO和H2的量快速增加,并在800℃取得最大值;停留时间的过度延长不利于合成气品质的提高,由于生物油的含氧量较高,气化剂O2的加入对合成气中可燃气含量的提高不利。

The gasification behavior is studied in a fixed bed gasification reactor under variant conditions e. g. different temperature, resident time, and gasifying agents, etc. , and the gas products involved is checked. It＇s observed that the yields of CO and H2 increase with gasification temperature increasing from 600℃ ,and the maximum value can be gotten at 800℃. The extension of resident time is not favorable for the upgrading of syn-gas quality.As the high oxygen content of bio-oil,the addition of gasify agent （O2） shows some negative influence on the evolving of combustible gas of H2, CO and CH4.
