Method for preparing activated coke having high desulfurization activity

The invention discloses a method for preparing activated coke having high desulfurization activity, belonging to the technical field of activated coke production, relating to a production method of the activated coke. The method comprises the following steps: (1) raw coal crushing: crushing the raw coal into raw coal particles having a particle size of less than 15-20 mm; (2) grinding: mixing theraw coal particles with a catalyst according to a weight ratio of 60-80:1-2 to prepare composite coal dust at 150-200 meshes; (3) kneading: mixing the composite coal dust with a binder according to aweight ratio of 61-82:5-25 and kneading to obtain a mixed material; (4) molding: mixing the mixed material with water according to a weight ratio of 66-107:8-25, and carrying out compression molding to obtain formed coke; (5) drying; (6) carbonizing; (7) activating; and (8) packaging. The method increases the comprehensive properties of the coal resource, has no influence on the environment, and widens the application and
