炭化温度对红柳林煤温和液化-炭化耦合转化产物的影响

Effects of carbonization temperature on the products from integrated mild-liquefaction and carbonization process of Hongliulin coal

    摘要
  • 摘要: 在炭化温度为430-600 ℃研究了红柳林煤温和液化-炭化耦合转化过程的产物分布及理化性质。结果表明，半焦产率达40.64%-53.02%，有机液相产率达30.89%-36.98%，正己烷可溶物产率达29.74%-33.28%；在较低温度下炭化温度升高有利于正己烷可溶物产率提高，而在较高炭化温度下则相反；430 ℃炭化温度下半焦表现出较强黏结性，550 ℃炭化温度下半焦的黏结性消失，挥发分降至10%左右。通过调节炭化温度可使半焦定向用于配煤炼焦或无烟煤原料。

     

    Abstract: The integrated mild-liquefaction and carbonization experiments of Hongliulin coal were conducted at 430-600 ℃, and distributions and physico-chemical properties of the obtained products were investigated. The results show that the yields of semi-cokes, organic liquid products and n-hexane soluble organic products were up to 40.64%-53.02%, 30.89%-36.98% and 29.74%-33.28%, respectively. The increasing carbonization temperature in the relatively low temperature range was favorable for the elevated yield of n-hexane soluble organic products, while at relatively high temperature presenting an opposite one. The semi-cokes obtained at 430 ℃ presented a strong caking property, while those at 550 ℃ showed no caking property, and the content of their volatile matters decreased to about 10%. It is suggested that the produced semi-coke could be directionally utilized as blending coal in coking or smokeless fuel by adjusting carbonization temperature.
