在生物质气流床（5 kg/h）气化和熔融盐调质净化装置上，进行了熔融盐对高含氮废弃物气流床气化产气的调质与污染物脱除实验，考察了不同熔融盐温度、不同静液高度对出口气体调质和含N、S、Cl污染物脱除特性的影响。结果表明：经过熔融盐调质后，产气中CO与CO2浓度下降，H2浓度明显上升。当温度从380℃升高至580℃时，H2/CO值提高至7.3。随着静液高度的提高，出口气体中CO2与CO浓度下降，H2浓度由30.1%提高至36.8%；熔融盐对高含氮废弃物气流床气化产气中含N、S、Cl污染物有较明显的脱除效果，H2S、SO2、HCl与含氮污染物中的HCN与NOx已完全脱除，当温度为580℃、静液高度为67.5 mm时，NH3脱除率达到96%。

In this work, a molten salt reactor coupling to a 5 kg/h biomass entrained flow reactor was used for conditioning and purification of syngas from nitrogen-rich wood waste. The effects of molten salt temperature and static liquid height on the outlet gas composition and desorption of pollutants of syngas were investigated. The results showed that the concentrations of CO2 and CO decreased sharply after the conditioning in molten salt, while the concentration of H2 rose obviously. When the temperature increased from 380oC to 580oC, the H2/CO ratio reached to 7.3. With the increasing static liquid height, the concentrations of CO2 and CO had a decrease, while the concentrations of H2 rose from 30.1% to 36.8%. The molten salt was an efficient technology for removing the nitrogenous, sulphureous and chlorinated pollutants in syngas obtained from entrained flow gasification of nitrogen-rich wood waste. H2S, SO2, HCl, HCN and NOx had been removed entirely. When temperature reached to 580oC, and static liquid height was 67.5mm, the removal rate of NH3 had reached to 96%.
