摘要
在100mL固定床加氢实验装置上,采用自制的不同性质的加氢催化剂组合对云南解放军化肥厂鲁奇炉副产的宽馏分煤焦油进行了加氢改质的工艺研究.结果表明,反应压力、温度、空速和氢油比等参数对煤焦油加氢改质的影响显著,并在反应压力12.0MPa,温度360℃,液时空速1.0h-1和氢油比1200∶1的优化条件下通过加氢改质和产品分馏,可以获得约9%的小于160℃石脑油馏分、78%的160℃～350℃柴油馏分和13%大于350℃尾油馏分.实验装置连续运行了1114h后仍能保持稳定,催化剂表现出良好的活性和稳定性.
Hydro-upgrading of Lurgi furnace wide distillation range coal tar from Yunnan Jiehua Company was carried out on 100 mL hydrogenation unit using different property self-made hydrogenation catalysts.The results revealed that the reaction temperature,pressure,volume ratio of hydrogen to oil and liquid hourly space velocity （LHSV） had great effect on catalytic performance of the catalysts.Under the optimized conditions of 12.0 MPa,360 ℃,1.0 h-1 and volume ratio of hyrdogen to oil 1 200：1,the hydrogenation products contains about 9% of naphtha,78% of diesel oil and 13% of hydrogenation tail oil.Hydrogenation unit realized stable operation and the catalysts exhibited high activity and stability lasted for about 1 114 h without obvious deactivity.
