摘要:
以陕北中低温全馏分煤焦油为原料,进行了悬浮床加氢连续进料中试试验,考察了反应温度、空速、催化剂加入量等工艺条件对加氢反应的影响。结果表明:在反应温度445 ℃、反应压力20 MPa、空速0.5 h-1、催化剂加入量(占煤焦油的质量分数)2%、氢油比(氢气体积与煤焦油质量比)2 000 L/kg的优化工艺条件下,重组分转化率、沥青质转化率、液体收率、气体收率依次为84.72%,85.96%,92.45%,5.53%。
Abstract:
The continuous pilot-scale test of hydrogenation in suspension bed was carried out by using medium-and low-temperature coal tar in northern Shaanxi as raw materials, and the effects of reaction temperature, space velocity, catalyst dosage and other process conditions on the hydrogenation reaction were investigated. The results showed that under the optimized process conditions that the reaction temperature was 445 ℃, the reaction pressure was 20 MPa, the space velocity was 0.5 h-1, the catalyst addition (mass fraction of coal tar) was 2%, and the hydrogen oil ratio (the ratio of hydrogen volume to coal tar mass) was 2 000 L/kg, the conversion rate of heavy components and asphaltene was 84.72% and 85.96%, and the yield of liquid and gas was 92.45% and 5.53% , respectively.
