连续重整装置加工催化裂化汽油的工业试验

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.

Industrial test of processing catalytic cracking gasoline in continuous reforming unit

The industrial test of processing catalytic 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,desulfuriztion and denitrification),the performances of the suitable fraction(raw gasoline) distillated from FCC gasoline could meet the requirement of reforming feedstock.When the blending ratio of the raw gasoline were 20%-50%,compared with processing naphtha,the reforming temperature of WAIT and WABT both increased,the total temperature drop decreased 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 depentanized oil and hydrogen had no change basically.
