一种分级分区转化催化裂化循环油的方法及装置
摘要：
本发明提供了一种分级分区转化催化裂化循环油的方法及装置。所述装置包括沉降器(1)、再生器(2)、提升管反应器(3)、催化加氢装置(4)和分馏装置(5)，再生器设置在沉降器底部，提升管反应器顶部的油气出口(31)与沉降器连接，提升管反应器底部通过斜管(6)与再生器底部连接，沉降器顶部与分馏装置连接，分馏装置与催化加氢装置连接以使得从分馏装置出来的轻循环油和重循环油能够合并后进入到催化加氢装置中；提升管反应器由上至下分别设置原料油反应区(32)和循环油反应区(33)，在原料油反应区和循环油反应区连接区域设置原料油入口(34)，在循环油反应区底部设置循环油入口(35)，并与催化加氢装置的循环油出口(41)连接。
摘要（英）：

The invention provides a method and device for converting catalytic cracking cycle oil in a grading and partition mode. The device comprises a settler (1), a regenerator (2), a riser reactor (3), a catalytic hydrogenation device (4) and a fractionation device (5). The regenerator (2) is arranged at the bottom of the settler (1), an oil gas outlet (31) in the top of the riser reactor is connected with the settler, the bottom of the riser reactor is connected with the bottom of the regenerator through an inclined pipe (6), the top of the settler is connected with the fractionation device, the fractionation device is connected with the catalytic hydrogenation device, and therefore light cycle oil and heavy cycle oil discharged from the fractionation device (5) can be combined and enter the catalytic hydrogenation device; the riser reactor is provided with a raw oil reaction area (32) and a cycle oil reaction area (33) from top to bottom. A raw oil inlet (34) is formed in the connection area of the raw oil reaction area and the cycle oil reaction area. The bottom of the cycle oil reaction area is provided with a cycle oil inlet (35) and connected with a cycle oil outlet (41) in the catalytic hydrogenation device.
