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.

摘要： Method for preparing material containing amorphous iron oxide hydroxide, the method including: mixing an aqueous ferrous salt solution and hydroxide solution or solid hydroxides at the temperature of below 70°C, filtering the reaction solution, washing the filter cake, preparing suspension solution of the filter cake, blowing an oxygen-containing gas into the suspension solution to oxidize the ferrous iron, and then filtering and drying. The material after being used as desulfurization agent can be repeatedly regenerated through oxidation in an oxygen-containing gas. A desulfurization agent, and methods for preparation and repeated regeneration thereof. The desulfurization agent contains the material and organic binders, and may also include a small amount of additives. The organic binders are selected from sodium carboxymethyl cellulose, sesbania powder, and cellulose powder, and the additives are selected from sawdust, rice husk power, and bran.

摘要： Methods for regenerating amorphous iron oxide hydroxide after being used as desulfurizer by (1) grinding a waste mixture into waste powder, wherein the waste mixture results from use of the composition comprising amorphous iron oxide hydroxide as desulfurizer; (2) preparing the waste powder into a suspension and charging the suspension with a gas containing oxygen to obtain a slurry comprising amorphous iron oxide hydroxide and elemental sulfur; and (3) placing the slurry or a solid resulting from filtering the slurry into a container and charging the slurry or the solid with air so that the elemental sulfur floats and the amorphous iron oxide hydroxide precipitates.
