Preparation method and application of magnetic iron oxide and desulfurizer containing the magnetic iron oxide as active component

摘要

A method of preparing magnetic iron oxide Fe_21.333O₃₂, which includes the steps of preparing a solid green rust and calcining the solid green rust to obtain the magnetic iron oxide Fe_21.333O₃₂. Also provided is the application of magnetic iron oxide Fe_21.333O₃₂ as an active material in desulfurization at a medium temperature. Also provided is a desulfurizer which uses magnetic iron oxide Fe_21.333O₃₂ and the application thereof. The present preparation method has simple steps and a short production period.
