Problems solved by technology
Although ordinary commercial activated carbon has a high specific surface area, developed microporous structure and large pore volume, it is directly used for CO 2 There are still many problems in gas capture, such as low adsorption capacity, poor selectivity, slow adsorption rate, and long recycling cycle
[0003] in the adsorption of CO 2 In the preparation process of activated carbon, the raw materials need to be crushed first. If the crushing process is not complete, the adsorption effect of activated carbon will be affected. Therefore, we have proposed a high-efficiency adsorption CO 2 The preparation method of activated carbon

The invention relates to the technical field of activated carbon processing and manufacturing, and discloses a preparation method of activated carbon capable of efficiently adsorbing CO2. The preparation method comprises the following steps: S1, placing anthracite in a crushing disc for crushing; S2, pretreating the crushed raw materials and bonding and forming the pretreated raw materials by using a binder; S3, drying the raw materials for 20 min to 40 min at the temperature of 60 DEG C to 100 DEG C; S4, raising the temperature to 400-600 DEG C under the protection of nitrogen, and carbonizing for 2-3h at the temperature. A motor is started to drive a supporting rod to rotate, that is, a stirring rod is driven to rotate through an arc-shaped plate when the supporting rod rotates, so that the stirring rod can smash anthracite in the crushing disc, and in the rotating process of the stirring rod, the stirring rod can deflect through the arc-shaped plate, the stirring rod extrudes the connecting plate due to friction, the stirring rod is limited through a connecting plate and a sliding rod, and therefore the extruding and smashing effect of the stirring rod on anthracite can be good.
Description
technical field [0001] The invention relates to the technical field of activated carbon processing and manufacturing, in particular to a high-efficiency CO adsorption 2 The preparation method of activated carbon. Background technique [0002] With the worsening of environmental problems such as global warming, the combustion of traditional fossil fuels produces a large amount of greenhouse gas CO 2 Capture and storage technology has gradually attracted people's attention. In addition to the traditional liquid ammonia absorption method, membrane separation, low-temperature distillation and other methods, the activated carbon adsorption method has the advantages of low cost, high adsorption capacity, high selective adsorption, and excellent cycle regeneration stability. 2 Gas capture is one of the most promising technologies among many technologies. Although ordinary commercial activated carbon has a high specific surface area, developed microporous structure and large pore...
