秸秆类生物质低温热解及混合气化的研究

The Study of Straw Biomass Pyrolysis and Co-gasification

生物质能源是一种重要的可再生能源,利用生物质和煤混合气化技术可以减少CO2的排放。研究了低温热解预处理对秸秆类生物质产物和气体浓度分布的影响,结果表明:经低温热解预处理后制得的生物焦的量和气体的浓度分布不仅与热解温度有关,而且与生物质种类的组成有很大的关系,考察了生物质焦和煤炭混合气化的热重试验,对混合气化反应性进行了有益的探索。

Biomass is a kind of significant renewable energy, using biomass and coal gasification technology can reduce CO2 emissions and consistent with sustainable development. In this paper, at first, the effects Of pyrolysis pretreatment on the straw pyrolysis products and gas concentration distribution were studied, the results showed that, after pretreatment by low temperature pyrolysis, the biomass coke and gas concentration distribution, not only had relations with the pyrolysis temperature, but also with biomass species composition,meanwhile gave some further discussions ; then the co-gasification between biomass coke and coal was analyzed by TG-DTG, cogasification reactivity was probed.
