摘要

生物质气化过程中副产的焦油不仅有腐蚀设备、堵塞管道等危害，而且会降低生物质气化效率，传统的物理处理与热裂解处理方法存在诸多不足。本文基于旋转弧热等离子体反应装置，以二氧化碳作为等离子介质，选取苯及苯萘混合物作为生物质焦油的模型化合物进行了气化实验，实现了向合成气的高效转化（碳收率可达到90%以上），初步显示了该路线的可行性。进一步分析了真实生物质焦油的物质组成，考察了二氧化碳等离子体对焦油的气化性能，焦油内的水分可作为气化剂，调节合成气中H

/CO的比例（0.3~1）。上述结果为生物质焦油无害化、资源化利用技术的发展提供了新的思路。

Abstract

The tar produced in the process of biomass gasification would not only corrode the pipelines and equipment

but also reduce the efficiency of biomass gasification. Traditional methods

such as physical treatment and thermal cracking

have deficiencies which severely restrict their application. This article achieved efficient transformation (carbon yield

90%) from benzene and naphthalene

regarded as model compounds of biomass tar

to syngas using CO

plasma on self-designed rotating arc plasma torch

proving the feasibility of CO

plasma treatment of biomass tar. Further analysis on the composition of practical biomass tar and the investigation of biomass tar gasification were carried out. Water content in biomass tar could be used as gasification agent and control the H

/CO scale (0.3—1). The above results provide new ideas for the development of biomass tar harmlessness and resource utilization technology.
