摘　　要：为生产符合要求的低硫船用燃料油,以硫含量为1.2%(w)的FCC油浆为原料,采用催化剂装填量为100 mL的上行固定床反应器开展了微界面强化FCC油浆加氢生产低硫船用燃料油工艺的研究。分别考察了反应温度、反应压力、体积空速和氢油体积比对微界面强化FCC油浆加氢反应的脱硫脱氮效率的影响,并与常规滴流床进行了对比。实验结果表明,在所考察的工艺条件下,微界面强化FCC油浆加氢工艺的脱硫效率显著高于常规滴流床加氢工艺,适当提高反应温度加快了多环噻吩类硫化物加氢脱硫本征反应速率,有利于发挥微界面强化技术的优势;在反应温度为370℃、反应压力为6 MPa、氢油体积比为400、体积空速为2.0 h^(-1)的优化条件下,微界面强化FCC油浆加氢工艺可生产出满足要求的低硫船用燃料油。To produce low-sulfur marine fuel oil that meets the requirements,using FCC slurry with a sulfur content of 1.2%(w)as the feedstock,the process of hydroprocessing FCC slurry to produce low-sulfur marine fuel oil was studied using an up-flow fixed bed reactor with catalyst of 100 mL loaded.The effects of reaction temperature,reaction pressure,volume space velocity,and hydrogen/oil volume ratio on desulfurization and denitrification efficiency of micro-interface intensified FCC slurry hydrotreating were investigated respectively,which were compared with that of conventional trickle bed process.The results show that under investigated technological conditions,the desulfurization efficiency of micro-interface intensified FCC slurry hydrotreating is higher significantly than that of the conventional trickle bed hydrotreating technique.Increasing reaction temperature in an applicable range can accelerate the intrinsic reaction rates of hydrodesulfurization of polycyclic thiophene sulfides and facilitate the advantage of the microinterface intensification technique.The qualified low-sulfur marine fuel oil can be produced with a micro-interface intensified FCC slurry hydrotreating technique under the optimized conditions of reaction temperature of 370℃,reaction pressure of 6 MPa,hydrogen/oil volume ratio of 400 and volume space velocity of 2.0 h^(-1).
