- Abstract
To prepare high intensity and desulfurized active coke, using Taixi anthracite as the main raw material investigate the influence of formulation of raw material coal, activation time and steam velocity on the preparation. The results show that, using pure clean anthracite as raw material, when the activation temperature is 850 °C, the activation time is 15 minutes, steam flow rate is 6.2 mL/min, the maximum iodine value of activated coke sample is 356 m/g, the minimum intensity is 99.18 percent. The desired iodine value ranges from 300 mg/g to 400 mg/g, the intensity should be greater than 99 percent. So it is good preparation technology parameters of activated coke. When the mass ratio of Taixi anthracite and other type of coal is 75 : 25, activation temperature is 850 °C, the activation time is 15 minutes, steam flow rate is 4 mL/min, the iodine value of activated coke sample is 320 mg/g, the intensity is 99.2 percent, the adsorption properties of activated coke and wear-resisting performance are the best.
