摘要:
采用添加KNO3修饰的铁矿石作为载氧体,以CO为燃料,在小型流化床反应器上进行化学链制氢试试验研究,探究了KNO3添加量及反应温度对载氧体还原过程及制氢过程的影响,并研究其循环特性. 研究结果表明:KNO3的添加使得铁矿石与其发生反应,生成的新相具有良好的催化还原效果,且随着KNO3添加量的增加,最终氢气生成量也随之增加;反应温度的增加加快了载氧体还原过程,使得最终氢气生成量也随之增加;循环过程中发现载氧体表现出良好的循环特性,氢气生成量保持稳定,表面形态没有发生明显变化;整个循环过程中发现了K的流失现象,尤其在第一次循环中流失较多,但在随后的循环中,K的催化效果保持稳定.
Abstract:
Experiments on chemical looping hydrogen generation were conducted in a batch fluidized bed reactor with iron ore decorated by KNO3 as the oxygen carrier and CO as the fuel. The effect of KNO3 ratio and reaction temperatures on reduction process and hydrogen generation process of oxygen carriers was examined, and cycle characteristics were also researched. The results indicate that KNO3 addition is reacted with iron ore, and the generated substances have good catalytic reduction effect. The final volume of generated H2 increases with the increase of KNO3 ratio. The reduction process of the oxygen carrier is speeded up by the increase of the reaction temperature, and the final volume of generated H2 also increases. In the cycle process, the oxygen carrier has good cycle characteristics. The cumulative volume of generated H2 remains stable. No obvious surface morphological change is observed. The phenomenon of K loss is observed during the cycle process, especially in the first cycle, but the catalytic effect of K remains stable in the subsequent cycle.
