摘要
对神华2-2煤在回转炉装置中进行了热力改性研究。结果表明,随着改性温度的升高,煤中氧含量和O/C原子比逐渐降低,煤的比表面积、总孔容、润湿热等指标在250℃存在一个极小值;热力改性能显著改善神华煤的成浆性,随着改性温度的升高,制浆浓度不断提高。
A thermal modification research was conducted in a rotary oven device with Shenhua 2-2 coal.The results showed that with the temperature for the modification increased,the oxygen content and O/C atom in the coal will be decreased.The surface area rate,total porosity volume,moisture thermal and other index will have a ultra small value at the temperature of 250℃.The thermal modification can obviously improve the slurry preparation of Shenhua coal.With the modification temperature increased,the density of the...
