摘　　要：高硫渣油深度加氢脱硫过程中,最难脱除的含硫化合物因有侧链取代、空间位阻效应强而最难转化,深度脱硫过程中,催化剂上金属(镍+钒)沉积及积炭均会加快。针对加氢脱金属剂及加氢脱硫降残炭剂分别开展级配比例的研究,结果表明:脱金属率随反应物流在脱金属催化剂上停留时间的增加而增加,脱硫率随反应物流在脱硫降残炭剂上停留时间的增加而增加,但在达到一定停留时间后的增加趋势均明显变缓;所开发的新型渣油加氢脱硫降残炭剂初始加氢脱硫活性不高,随着运行时间的延长活性有所提升并保持稳定。基于级配研究结果及加氢脱金属脱硫剂的特性,开发了新型高硫渣油深度加氢脱硫催化剂级配技术,并在高硫渣油固定床加氢装置上进行了工业应用。结果表明,新型级配催化剂具有良好的加氢脱硫活性及优异的稳定性,该固定床渣油加氢装置在确保催化裂化装置原料供应的前提下能够稳定生产低硫重质船用燃料油调合组分。In the process of deep hydrodesulfurization(HDS)of high sulfur residue,the refractory sulfur-containing compounds were most difficult to remove because of side chain substitution and strong spatial position effect,and metal(Ni+V)and carbon deposition on catalysts were accelerated.The research on catalyst grading ratio of hydrodemetallization(HDM)catalyst and HDS&HDCCR(hydrodeconradson-carbon-residue)catalyst for reducing carbon residue was carried out.The results showed that the HDM rate increased with the increase of the residence time of the reaction stream on the HDM catalyst,and the HDS rate increased with the increase of the residence time of the reaction stream on the HDS&HDCCR catalyst,but after reaching a certain residence time(inflection point value),the increasing trend obviously slowed down.The new HDM&HDS Catalyst had low initial HDS activity,and the activity increased and remained stable with the extension of operating time.Based on the research results of the gradation and the characteristics of HDM&HDS catalyst,an advanced catalyst gradation technology for high sulfur residue deep HDS was developed and applied in the fixed bed residue hydrotreating unit.The results showed that the new technology had good HDS activity and excellent stability,and the fixed bed residue hydrotreating unit could stably produce blending components of low sulfur heavy marine fuel on the premise of ensuring the supply of FCC feedstocks.
