生物质等离子体气化研究

THE STUDY ON THE PLASMA GASIFICATION OF BIOMASS

在热等离子体提供的高温、高能量反应环境中,进行生物质的快速热解气化研究。生物质的等离子体 热解气化产物由固体残渣和气体组成,无焦油存在。气体产物中主要以化学合成气(H2和CO)为主。增加水蒸气 流量,H2和CO含量之和均在96％以上,且V(H2)/V(CO)比率为0．90-1．15,气体产率达到2．0 L/g,碳的气相 转化率很高。

A plasma reactor which has high temperature and high enthalpy was used to study the biomass gasification. The product included solid char and gas. No tar was detected.The main gas product was the Synthesis gas （H2＋CO）.With the increasing of the steam flow, H2/CO molar ratio ranged from 0.90 to 1.15.The gas yield was about 2L/g （biomass） and the combined volume of H2 and CO was 96% .The gas conversion of carbon was very high.
