摘要：
Methods for preparing a composition containing amorphous iron oxide hydroxide. Methods for regeneration of the amorphous iron oxide hydroxide after it has been used as desulfurizer. Regenerable desulfurizer with high sulfur capacity containing amorphous iron oxide hydroxide, not less than 88% w/w, and organic binder not less than 7% w/w. The organic binder is sodium carboxymethylcellulose, sesbania powder, cellulose powder, or a mixture thereof. A method for preparing the desulfurizer. A method for regenerating the waste agent produced after the desulfurizer and the composition containing the desulfurizer are used as desulfurizer. This method allows the desulfurizer and the composition containing the desulfurizer to be regenerated and reused avoiding the need for landfill disposal and environmental pollution.
