Co-Hydrogenation Behavior of Hami Coal with Tahe Residue

Funds: The project was supported by the National Key Research and Development Program of China(2016YFB0600303)
  • 摘要: 采用高压釜考察了哈密煤与塔河重油单独加氢反应性能和共加氢反应性能,探索了哈密煤与塔河渣油共加氢的可行性技术路线。实验结果表明:哈密煤具有良好的液化反应性能,合适的反应温度为445 ℃,在445 ℃、9MPa时转化率达98.74%,油收率达68.54%;塔河渣油单独加氢在较低反应温度时表现出明显的结焦倾向,很难实现加氢轻质化,430 ℃时,转化率仅有66.38%,轻质油收率也仅有50.01%,结焦率却高达9.45%,随着反应温度升高,结焦速率加剧;哈密煤与塔河渣油共加氢时转化率较低,结焦明显,煤/油比为40/60时转化率为97.79%,油收率为73.36%。在共加氢体系中引入具有供氢性能溶剂能够有效抑制生焦,提高转化率,实现共加氢轻质化,在煤粉添加量为45%时,塔河渣油合适的添加量为20%,原料的转化率达到98.38%,油收率为74.82%。
