摘要

摘要: 在固定床装置中进行了熔融盐对生物质粗燃气组分调整实验，考察了反应温度、静液高度和表观气速对熔融盐中出口气体组分、NaOH消耗率、熔融盐饱和吸收时间的影响。结果表明，400~600 ℃下，熔融盐中NaOH消耗率随温度的升高由59%升至83%，且单位质量熔融盐处理粗合成气量随温度的升高由0.42 m³/kg升至0.48 m³/kg；气体中CO转化率和出口气体平均H₂/CO体积比均随反应温度、静液高度的提高而升高，随表观气速的增加而降低。

Abstract: The modification of biomass fuel gas was studied in a fixed reactor with a certain amount of molten salts. The effects of temperature, static liquid height and superficial gas velocity on the outlet gas composition, the NaOH consumption, and the saturable absorption time of molten salts were investigated. The results show that the NaOH consumption increases from 59% to 83% and the biogas handling volume per unit molten salts is enhanced from 0.42 m³/kg to 0.48 m³/kg by elevating the temperature from 400 to 600 ℃. The CO conversion and the H₂/CO volume ratio of outlet gas both increase with the increasing of temperature and static liquid height, and decrease with the increasing of superficial gas velocity.
