摘　　要：在不同煤种及炭化条件下,于一间歇流化床上制备活性焦(AC)。使用XPS等分析手段考察不同制备条件下制得的活性焦表面化学性质的差异。研究结果表明,煤种不同制得的活性焦的表面性质相差较大;炭化条件(炭化温度400—800℃、炭化时间0—60min)对最终制得的彬县煤活性焦表面化学性质影响很小。The effects of coal type and carbonization conditions on the surface properties of the activated cokes (prepared) on a batch fluidized bed were investigated using X-ray photoelectron spectroscopy (XPS) and other (analytical) methods. It is found that the surface properties of the activated cokes prepared from different coals differ from each other greatly because of the different contents of volatile and oxygen in the coals, and the carbonization conditions (temperature and time) have a little effect on the surface properties of the activated coke prepared from Binxian coal.
