Effects of addition of Mo on the sulfidation properties of Fe-based sorbents supported on fly ash during hot coal gas desulfurization

摘要：

This paper studies the influence of the addition of Mo on the sulfidation performance of Fe-based sorbent supported on fly ash for hot coal gas desulfurization.Sorbent samples were prepared using physical mixing method with different Mo oxide content.The sulfidation experiments were carried out in the temperature range of 400-600℃.Gas compositions were analyzed using a GC.The structure and morphology of sorbent samples before and after sulfidation were examined by using SEM,XRD and compressive strength was also measured.The experimental results show that the fly ash supporter has some capability for sulfur removal from the hot coal gas.The addition of Mo may effectively improve the desulfurization efficiency and increase the compressive strength of iron-based sorbents
