摘要

我们提出了一种在石英反应器中通过感应加热从生物质生产不同H2与CO比例合成气的方法。为了将热量传递给生物质,我们添加了铁屑或钢球,并将其均匀地分布在生物质床中。在使用铁屑的情况下,H2 与 CO 的摩尔比为 2.3:1,而使用钢球则将这一比例降至 1:1.4,从而使产气量增加了 22 摩尔%。在生物质和钢球混合物上方的感应加热区域多加一层铁屑,可促进重焦油的部分分解,使气体产物的产量再增加 20.7 摩尔%,H2 与 CO 的摩尔比达到 1.6:1。挥发性化合物在铁屑表面的二次反应生成了对二甲苯和邻二甲苯。气相色谱和气相色谱-质谱对气态和液态热解产物的成分进行了研究。

A method for hydrogen-enriched syngas production from biomass via induction heating
We propose a method for production of syngas with different H2 to CO ratios from biomass via induction heating in a quartz reactor. To transfer heat to the biomass, iron filings or steel balls were added and evenly distributed in the biomass bed. In the case when iron filings were used, the molar ratio of H2 to CO was 2.3:1, while the use of steel balls reduced this ratio to 1:1.4, resulting in a 22 mol.% increase in gas yield. An extra layer of iron filings located in the induction heating area above the mixture of biomass and steel balls facilitated partial decomposition of the heavy tar, increasing the yield of gaseous products by another 20.7 mol.% with the molar ratio of H2 to CO reaching 1.6:1. Secondary reactions of volatile compounds on the surface of iron filings resulted in the formation of p-xylene and o-xylene. The composition of gaseous and liquid pyrolysis products was investigated by GC and GC–MS.
