固体氧化铁脱硫剂长期以来因硫容量低，用于高含硫气体时，存在着在高空速下气体净化度不高的问题，限制了氧化铁脱硫剂的应用。
Application of solid ferric-oxide desulfurizers has been limited for a long time because the gas with high sulfur content can't be purified sufficiently under high space velocity.
此外，本发明还提供可用作所述脱硫方法中使用的脱硫剂的构成成分的固体酸及其制造方法。
There are also provided a solid acid useful as a constituent of the desulfurizing agent for use in the desulfurization method, and a process for producing the solid acid.
