Embodiment 1

[0020] The preparation method of a kind of metal ion modified activated carbon desulfurizer provided by the embodiment of the present invention may comprise the following steps:

[0021] Step S10: Select 5-mesh granular coal-based activated carbon as a raw material, put the granular coal-based activated carbon and water into an autoclave in an equal volume, and conduct a hydrothermal chemical reaction at 3 MPa for 2 hours.

[0022] Step S20: After the hydrothermal chemical reaction is completed, the activated carbon is cooled and taken out, placed in an ultrasonic instrument for 2 hours, filtered, and dried at 120°C.

[0023] Step S30: Weigh a certain amount of copper sulfate and dissolve it in a certain amount of water. After fully dissolving, slowly add concentrated ammonia water until the formed metal ion precipitate is just completely dissolved, that is, the M(NH3)x+ solution is prepared.

[0024] Step S40: Take 50 g of activated carbon that has been hydrothermally treated...

Embodiment 2

[0026] The preparation method of a kind of metal ion modified activated carbon desulfurizer provided by the embodiment of the present invention may comprise the following steps:

[0027] Step S10: Select 10-mesh granular coal-based activated carbon as a raw material, put the granular coal-based activated carbon and water into an autoclave in an equal volume, and conduct a hydrothermal chemical reaction at 4 MPa for 1 hour.

[0028] Step S20: After the hydrothermal chemical reaction is over, cool the activated carbon, take out the activated carbon, place it in an ultrasonic instrument for 2 hours, filter it, and dry it at 110°C.

[0029] Step S30: Weigh a certain amount of copper sulfate and dissolve it in a certain amount of water. After fully dissolving, slowly add concentrated ammonia water until the formed metal ion precipitate is just completely dissolved, that is, the M(NH3)x+ solution is prepared.

Abstract

The embodiment of the invention provides a preparation method of a metal ion modified activated carbon desulfurizer, and belongs to the technical field of desulfurizers. The preparation method comprises the following steps: isopyknic granular coal-based activated carbon and water are placed in a high-pressure kettle, and a hydrothermal chemical reaction is carried out under a certain pressure; cooling, taking out the activated carbon, performing ultrasonic treatment in an ultrasonic instrument for a certain time, and then filtering and drying; metal salt is dissolved in water, strong ammonia water is slowly added after the metal salt is fully dissolved until generated metal ion precipitates are just completely dissolved, and an M (NH3) x < + > solution is prepared; and putting the filtered and dried activated carbon into a conical flask, vacuumizing, dropwise adding an M (NH3) x < + > solution until the M (NH3) x < + > solution is completely dropwise added, standing, drying to a constant weight, and calcining in a tubular furnace to obtain the metal ion modified activated carbon desulfurizer. The preparation process can be simplified, the desulfurization precision of the activated carbon desulfurizer is improved, and the desulfurization capacity is increased.

Description

technical field [0001] The invention relates to the technical field of desulfurizers, in particular to a method for preparing a metal ion-modified activated carbon desulfurizer. Background technique [0002] Activated carbon is an adsorbent with wide pore size distribution, large specific surface area, complex pore structure, rich surface active groups and simple operation. It plays an important role in the adsorption of hydrogen sulfide and other gases, and is often used in various industrial gas desulfurization. Such as coal gas desulfurization. [0003] However, the desulfurization accuracy of ordinary activated carbon is not ideal, so it cannot be used for fine desulfurization. Only modified activated carbon can achieve a certain effect of detoxification. Therefore, modified activated carbon has attracted the attention of more and more domestic and foreign scholars. The preparation method of the modified activated carbon desulfurizer in the prior art is complicated, a...
