RENEWABLE AND REUSABLE DESULFURIZER AND PREPARATION METHOD AND REGENERATION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2010/139104

Kind Code:

A1

Abstract:

A renewable and reusable desulfurizer comprises amorphous iron oxyhydroxide of no less than 88wt% and organic binder of no less than 7wt%, wherein the organic binder is selected, one or more, from the group consisting of sodium carboxylmethyl cellulose, sesbania powder and cellulose powder. The desulfurizer is prepared by mixing, shaping, and air seasoning or drying. A method for regenerating the desulfurizer is also provided. The desulfurizer, with high sulfur content, may be reused after regeneration so as to make efficient use of the desulfurizer resources without polluting the environment.
