Energy and environmental issues are urgent issues to be addressed. Effective use of herbaceous and woody biomass is becoming widely recognized as one of the leading choices. Gasification technology of biomass would be at its center. To do so, is also present (tar) failure that is not insurmountable yet. In this study, using a floating externally heated high-calorie gasification method, was operated biomass raw material type, particle size, temperature, and reaction time. By revealing the behavior of trace components contained in the biomass, it was possible to obtain a gasifier design and operation method of practice.

能源和环境问题是亟待解决的问题。有效利用草本和木本生物质正被广泛认为是主要的选择之一。生物质气化技术将是其核心。要做到这一点，也是目前（焦油）的失败，这不是不可逾越的。本研究采用浮动外热式高热量气化法，考察了生物质原料种类、粒径、温度、反应时间等因素对气化效果的影响。通过揭示生物质中所含微量组分的行为，有可能获得实用的气化炉设计和操作方法。
