| 20090197759 | METHOD FOR TREATING SATURATED ACTIVATED COKE - A method for treating saturated activated coke comprises the following steps: A) The saturated activated coke is subjected to a dehydration treatment so that the water content in the activated coke is ≦25%; B) The product obtained from step A is dried at a starting temperature of 120° C.-150° C.; C) The product obtained from step B is subjected to dry distillation and the condition of the dry distillation is that: by heating to a final temperature for the drying of 500° C.-600° C. at a speed of 4° C.-10° C./min and maintaining for 10-60 minutes, the organics adsorbed on the surface and in the pores of the activated coke is cracked, volatilized and carbonized; D) The product obtained from step C is activated and the activation condition is that: after heating to 800° C.-950° C. at 2° C.-8° C./min, a stream is supplied, wherein the weight ratio of the activated coke to the stream is 1:0.5-5 and the activation time is 0.5-2 h. The activated coke after several times of treatment can be used as the fuel. | 08-06-2009 |
