摘要/Abstract

摘要： 针对改质沥青甲苯不溶物和喹啉不溶物偏高的问题进行了分析，找出了影响改质沥青质量的原因，采取了降低炉顶空间温度、减小高压氨水压力等措施，提高了改质沥青质量。

关键词: 改质沥青, 炉顶空间温度, 氨水压力

Abstract:

Analysis is made for the high content of toluene insolubles and quinoline insolubles in the modified pitch and cause of impacting the quality is found. Measures have been taken to improve the quality of the modified pitch,such as lowering the free space temperature on oven top and reducing the pressure of HP ammonia liquor,etc..

Key words:

"> Modified pitch, Free space temperature on oven top, Pressure of ammonia liquor
