Abstract: 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.

Abstract: The present invention provides a process for preparing ball-type desulfurizer with high sulfur capacity, comprising the following steps: placing initial balls in a rolling equipment; wetting the surface of the initial balls with an aqueous solution of an organic binder; then alternately adding non-crystalline iron oxide hydroxide and the aqueous solution of the organic binder to gradually form small balls of non-crystalline iron oxide hydroxide with high sulfur capacity and different diameters; and adjusting the shape of the small balls and then roasting or naturally drying the small balls. In the desulfurizer prepared by this method, the initial balls constitutes 0.98 wt %-9.03 wt % of the desulfurizer, the non-crystalline iron oxide hydroxide constitutes 90.29 wt %-98.62 wt % of the desulfurizer, and the organic binder constitutes 0.58 wt %-0.89 wt % of the desulfurizer.
