In the invention, carbon dioxide is selected as an activating agent, so that carbonization and activation are simultaneously carried out, and the one-step preparation of the activated carbon is realized. The reaction principle is that firstly, pores which are formed during carbonization but are blocked are opened, namely, at high temperature, activated gas reacts with disordered carbon atoms first. Then the opened pores are continuously enlarged, communicated and developed to the depth, and carbon atoms at the edges of the pores are easy to react with water vapor and activated gas due to the unsaturated structure, so that the pores are continuously enlarged and developed to the depth. Finally, new pores are formed, and as the activation reaction continues, new unsaturated carbon atoms or active sites are exposed on the surface, so that the new active sites can be combined with CO2The reaction proceeds and this uneven burning of the activated carbon surface continuously leads to the formation of new pores.
Compared with the reaction of carbon dioxide and water vapor with coal powder or coal, the method has the advantages that the reaction of carbon dioxide and coal slurry is adopted, on one hand, the amount of the introduced proper water vapor does not need to be calculated deliberately, only the water-coal ratio in the coal slurry needs to be calculated, and the influence on the aperture development of the activated carbon caused by too much or too little introduced water vapor is avoided; in the second aspect, carbon dioxide reacts with coal slurry in a settling furnace at high temperature, so that coal is prevented from being burnt at the moment of high temperature contact in the water gasification process, the yield of activated carbon is improved to one third from one tenth of the yield of the prior art, and the investment cost is reduced.
