纯煤焦油生产高品质N375炭黑研究

The Exploration of Pure Coal Tar to Produce High- quality N375 Carbon Black

将传统的煤气进料方式由轴向进料改为径向进料,同时将原料油罐温度提高25%,通过油预热器使原料油预热温度提高20%,除此之外,将入炉油压提高18%,可以由纯煤焦油生产符合GB 3778-2011的高品质N375炭黑。

By changing the traditional way of coal gas feed from temperature at 25%, increasing the boiling oil temperature at 20% quality N375 carbon black which satisfied the standard of GB 3778 axial to radial, enhancing the raw oil storage tank by the oil preheater and pressure at 18%, the high - -2011 was produced by pure coal tar.
