摘要：在煤直接液化中 ,煤浆黏度变化是一个十分重要的工艺性问题 ,至今尚未得到充分研究 .研究了在常压、2 0 0℃以下三种煤与四氢化萘制成煤浆的黏温变化 .研究发现 :随温度的增加 ,三种煤样的黏度呈先降后增的变化趋势 ,其黏度值都在 1 60℃时达到最低 ,1 60℃～ 2 0 0℃黏度迅速增加 .煤的溶胀及溶出物是升温过程中煤浆黏度变化趋势的主要影响因素 .
Viscosity change of coal slurry is an important technological issue during direct coal liquefaction,and up to now it hasnt been fully researched.Here the viscosity-temperature characteristic of coal-oil slurry made by three kinds of coal and tetralin was studied at normal pressure,below 200 ℃.The results show that the viscosity of coal slurry first decreases and then increases.The viscosity is the smallest at 160 ℃ and increases swiftly from 160 ℃ to 200 ℃.Coal swelling and extraction are the major factors that affect the viscosity change during heating.
