[0026] In some embodiments, the preparation method of the composite desulfurization and mercury removal agent comprises the following steps:
[0027] (1) Mix potassium chromate, calcium manganate, and cobalt oxide evenly, add water so that the water content is 15-27%, and under vacuum conditions, adopt a temperature of 100-120° C. for 20-40 minutes;
[0028] (2) Prepare the pyrolusite into powder, and add the material of step (1) into the pyrolusite powder, add water and knead it into mud, prepare the mud into particles with a diameter of 0.04-1.7mm, and place it in the presence of nitrogen , at 150-240°C for 0.8-1.3h, then add ethylenediamine.
[0029] In some embodiments, in the steps (1) and (2), the water contains potassium hydroxide or lithium hydroxide with a mass concentration of 3-7%. The alkali metal activates the manganese component in the manganese-based desulfurization and mercury removal agent to increase the desulfurization and mercury removal rate.
