Solid desulfurating agent

Abstract

The invention relates to a solid desulfurating agent, comprising an active constitute cubic system crystalline phase Fe3O4, amorphism Fe2O3 and amorphism Fe2O3.H2O, and a paste product which is obtained from the reaction of assistant binder ferrous sulphate salt and calcium hydroxide; the invention further disclose a preparation method of the solid desulfurating agent on the basis of disclosing the constitutes of the solid desulfurating agent. The side pressure strength of the solid desulfurating agent prepared by the method in the invention can be as high as 85N / cm, and can be widely applied to the desulfurating technique of high temperature coal gasification materials.

Description

technical field

[0001] The invention relates to a solid desulfurizing agent that can be used for high-temperature desulfurization, and belongs to the technical field of desulfurization and purification. Background technique

[0002] With the increasing shortage of petroleum resources, the use of coal gasification products instead of petroleum as new energy and chemical raw materials has become a topic of widespread concern in the world. However, most coal gasification raw materials contain a large amount of hydrogen sulfide gas, which is likely to cause serious pollution to the environment; and the existence of hydrogen sulfide gas will also cause corrosion to the equipment used in the subsequent processing and utilization of coal gasification raw materials, and even affect industrial production. The catalyst is poisoned and deactivated, so in order to speed up the process of coal gasification products replacing oil, it is necessary to find an economical and efficient method...
