Abstract: The catalytic cracking performances of several propane deasphalted oil obtained in our earlier work were investigated in a fixed fluidized bed reactor at the reaction temperature of 490 ℃, catalyst to oil mass ratio of 5 (catalysts 80 g) and space velocity of 15 h-1. It was found that the propane deasphalting oil with the highest saturated fraction mass fraction of vacuum residuum was a good FCC feedstock. the product distribution and selectivity of the deasphalted oil from vacuum residuum blending FCC slurry oil were better than that from FCC slurry oil. But for the deasphalted oil from FCC, slurry oil had lower conversion and light oil yield, and the cracking performance was also poor.

Key words: Vacuum residuum, FCC slurry oil, Deasphalted oil, Catalytic cracking

摘要: 在前期丙烷脱沥青工艺得到不同脱沥青油的基础上,通过固定流化床反应装置,在反应温度490 ℃,剂油质量比为5(催化剂为80 g),空速15 h-1的实验条件下,研究了脱沥青油的催化裂化性能。结果表明,饱和分质量分数最高的减压渣油的丙烷脱沥青油是很好的催化裂化原料;减压渣油和减压渣油掺兑催化油浆所得的丙烷脱沥青油也具有较好的轻油选择性和产物分布;但催化油浆的丙烷脱沥青油作催化裂化原料时,其转化率、轻油收率最低,裂化性能较差。
