| 摘 要： | 在反应温度510 ℃，剂油比Cat/Oil=5（催化剂为5 g）,空速LHSV=15 h－1的实验条件下于重油微反装置中对几种脱沥青油的催化裂化性能进行了研究,并与掺兑减压渣油的VGO(减压馏分油)的裂化性能进行了对比。研究发现，减压渣油和掺兑催化油浆的减压渣油的丙烷脱沥青油具有较好的产物分布和选择性；而催化油浆的脱沥青油的裂化性能较差。

| Abstract: | Several deasphalted oil samples were obtained from vacuum residuum and FCC slurry oil deasphalted at continuous propane deasaphalting pilot equipment. Their catalytic cracking performances were investigated using a heavy oil micro-reaction apparatus at the condition of reaction temperature: 510 ℃, catalyst to oil ratio: 5.5 and space velocity: 15 h－1. The experimental results showed that the product distribution and selectivity of the deasphalted oil from vacuum residuum was better than that from gasoline while the deasphalted oil from FCC slurry oil was worse than gasoline. Meanwhile it was found that the catalytic cracking property of the deasphalted oil from vacuum residuum became worse with increasing its yield. |
