摘　　要：以5种不同的渣油为原料,从催化剂开发、催化剂级配、工艺条件优化、原料适应性考察等角度深入研究并开发了渣油深度加氢技术。结果表明:新开发的渣油深度加氢系列催化剂活性显著高于常规催化剂;反应温度是影响加氢深度最关键的因素;在优化的催化剂级配方案和工艺条件下,渣油深度加氢技术不仅可以显著提高原料中杂原子的脱除率,提高生成油的氢含量,还可以实现烃类定向转化多产化学品;高硫、低氮常压渣油更适宜采用渣油深度加氢技术生产优质催化裂解原料。Using five different kinds of residue as raw materials,the residue deep hydrotreating technology was developed from different perspectives such as catalyst development,catalyst grading technology development,process condition optimization,and raw material adaptability investigation.The investigation showed that the activity of the newly developed catalysts was significantly higher than that of the conventional catalysts,and the reaction temperature was the most critical factor affecting the hydrogenation depth.Under the optimized catalyst grading and process conditions,the residue deep hydrotreating technology achieved high-efficiency removal of heteroatoms and a significant increase in hydrogen content,and also realized the directional conversion of the dominant hydrocarbon which can produce more chemicals.The results also showed that the atmospheric residue with high sulfur and low nitrogen was suitable to be used as the feedstock of the residue deep hydrotreating technology to produce high quality catalytic cracking feedstock.
