The influence of the gasification temperature and Equivalence Ratio (ER) on the behavior of an industrial low-grade Solid Recovered Fuel (SRF) was investigated in an air bubbling fluidized bed. The studied SRF exhibits an intermediate composition between biomass-rich SRF and plastic-rich SRF. Its Lower Heating Value (14 MJ/kg) is low since its ash content is very high (35 wt%). But surprisingly, the Cold Gas Efficiency and the Carbon Conversion were relatively high with this type of low-grade SRF. As a result, the syngas produced is quite rich (LHV > 8 MJ/m3 STP) and it may be valorized in gas engines. H2S, HCl, HCN and NH3 in the syngas were analyzed. These results confirm that inorganic gases are an important issue for the valorization of SRF as fuel in gasification processes, even if significant parts of S, N and Cl are not converted into inorganic gases.

鼓风流化床中低级SRF的气化:永久性和无机气体的表征

在鼓泡流化床中研究了气化温度和当量比(ER)对工业低品位固体回收燃料(SRF)行为的影响。研究的SRF表现出介于富含生物质的SRF和富含塑料的SRF之间的中间组成。它的较低的发热量(14 MJ / kg)低,因为其灰分含量很高(35 wt%)。但是令人惊讶的是,使用这种类型的低等级SRF的冷气效率和碳转化率相对较高。结果,产生的合成气非常丰富(LHV> 8 MJ / m 3 STP),可以在燃气发动机中使用。H 2 S,HCl,HCN和NH 3在合成气中进行了分析。这些结果证实,即使大部分S,N和Cl未被转化为无机气体,无机气体对于气化过程中作为燃料的SRF的增值也是重要的问题。
