Abstract

The invention discloses a method for preparing a spheroidal high-sulfur-capacity magnetic iron oxide desulfurizing agent. The method comprises the following steps of: placing a female ball into rolling equipment, wetting the surface of the female ball through utilizing an organic binding agent water solution, alternately adding magnetic iron oxide Fe21.333O32 and the organic binding agent water solution, gradually forming a ball, so as to obtain spheroidal high-sulfur-capacity magnetic iron oxide Fe21.333O32 small balls with different diameters; naturally airing or drying the obtained small balls after shaping. According to the desulfurizing agent prepared by using the method: the female ball accounts for 0.1%-10% of the total mass of the desulfurizing agent, the magnetic iron oxide Fe21.333O32 accounts for87%-99% of the total mass of the desulfurizing agent, and an organic binding agent accounts for 0.5%-3% of the total mass of the desulfurizing agent. The preparation method provided by the invention has the advantages that the problems that the high-sulfur-capacity desulfurizing agent in the prior art is high in binding agent content, poor in water tolerance and poor in diffusion capability are solved, the prepared binding agent content is low, the water tolerance is good, and the diffusion ability is good.

Description

technical field [0001] The invention relates to a method for preparing a desulfurizing agent and a product thereof. Specifically, it is a method for preparing a spherical high-sulfur-capacity magnetic iron oxide desulfurizer and its product. Background technique [0002] As we all know, sewage treatment, papermaking, petroleum processing, chemical fertilizer manufacturing, chemical fiber manufacturing and some chemical raw material manufacturing industries discharge a large amount of hydrogen sulfide, which not only causes environmental pollution, but also easily leads to catalyst poisoning and deactivation, so reducing hydrogen sulfide in industrial production The amount of emissions has become one of the major problems that need to be solved in today's world industrial production. [0003] At present, in order to effectively reduce the impact of hydrogen sulfide on industrial production and the environment, a variety of hydrogen sulfide desulfurizers have been introduced ...
