摘　　要：生物质气化过程中产生的焦油问题对整个气化系统的效率以及最终商业化发展有着重要的作用,焦油的危害在于其冷凝之后对反应设备有较大的腐蚀性而且对后续的反应也有影响。因此,生物质气化过程中去除焦油十分必要。本文综述了气化过程中温度、停滞时间、催化剂种类等因素对生物质气化过程中焦油产量的影响,并且详细介绍与对比了现实工业生产中去除焦油的几种常用方法。The elimination of tar in biomass gasification processes plays a significant role in improving the efficiency of the gasification system,and the management itself will pose a great effect on the final commercialization. With the condensation of tar,it will not only erode reactors,but also affect the subsequent reaction process. So it is indispensable to handle with the tar through the gasification processes. The influencing factors to the output of the tar in the gasification processes were summarized,such as temperature,stagnation time and catalyst,the measures of tar elimination in the industrial production were elaborate.
