| 摘 要： | 在固定床内进行了熔融盐粗燃气成份调质实验,对熔融盐粗燃气调质实验的运行稳定性、反应过程对熔融盐的物性变化的影响、粗合成气成份对调质实验的影响等问题进行了考察.结果分析表明,350～500℃所有实验工况下,熔融盐均能有效的吸收粗燃气中的CO2,得到的合成气中CO2体积分数在2％附近,熔融盐处理技术能有效增加合成气中H2体积分数,降低CO体积分数,连续运行11h后合成气成份仍相对稳定.实验完成后熔融盐中Na2CO3分布呈现中部高两头低的分布规律,Na2CO3和NaOH比例变化时熔融盐熔点变化较小.这些特性都表明熔融盐粗燃气成份调质适合作为气化、热解制备合成气的后续工艺,提升燃气品质.

| Abstract: | The modification of raw fuel gas composition of molten salts is carried out in fixed reactor.The effects of temperature,flux,bubble diameter,position of interface and inlet gas composition on the composition of syngas and physical properties of molten salts are investigated.The results show that,under all experiment cases with temperature range of 350-500℃,CO2 is effectively absorbed by molten salts,and the volume fraction of CO2 in the syngas is around 2%.After 11 hours’ continuous operation,the composition of syngas is relatively stable.After the experiment,Na2CO3 concentration is higher in the middle and lower at the end of the molten salts.The melting point of the molten salts has little change for different Na2CO3 and NaOH ratio.The modification of raw fuel gas composition of molten slats can be a suitable follow-up procedure for gasification or pyrolysis to upgrade syngas quality. |
