连续重整装置加工催化裂化汽油的工业试验

Industrial test of processing catalytic cracking gasoline in continuous reforming unit

介绍了中国石化北京燕山分公司60万t/a连续重整装置加工催化裂化(FCC)汽油的工业试验情况。结果表明,FCC汽油蒸馏后所得适宜馏分经深度加氢脱硫、脱氮并使烯烃饱和后,其性质符合重整工艺的要求。当加氢粗汽油的掺炼比在20%～50%时,与加工正常铂料相比,重整反应WAIT和WABT温度均有所提高;总温降降低18.56～43.20℃,氢气收率降低0.16%～0.28%,且掺炼比例越高,二者的降低幅度越大;脱戊烷油收率约降低1个百分点;产品脱戊烷油及氢气的性质基本无变化。

The industrial test of processing catalyt- ic cracking（FCC） gasoline in a 600 kt/a continuous reforming unit of Yanshan Petrochemical Company, SINOPEC was introduced. The results showed that after deep - hydrogenation （ olefin saturation, desul- furiztion and denitrifieation）, the performances of the suitable fraction （raw gasoline） distillated from FCC gasoline could meet the requirement of refor- ming feedstock. When the blending ratio of the raw gasoline were 20% -50% , compared with process- ing naphtha, the reforming temperature of WAIT and WABT both increased, the total temperature drop de- creased by 18.56 -43.20 ℃ ,the yield of hydrogen decreased by 0. 16% - 0.28% , and the higher the blending ratio was, the bigger decreasing degree was. The yield of depentanized oil decreased by about 1 percent point, and the performance of depen- tanized oil and hydrogen had no change basically.
