The domestic semi-regenerative catalytic reformers established in 1960s and 1970s are mostly 100000 - 150000 tpy ones with aromatics extraction using diethyl glycol as solvent. These units have small capacity, high energy consumption and low liquid preduct yield. On the other hand, the units have short revamping period, low cost, fast outputing, good economic benefits and should be listed as the emphasis of debottlenecking in capacity expansion of the catalytic reformers. Now it is also a shortcut for gasoline...

The domestic semi-regenerative catalytic reformers established in 1960s and 1970s are mostly 100000 - 150000 tpy ones with aromatics extraction using diethyl glycol as solvent. These units have small capacity, high energy consumption and low liquid preduct yield. On the other hand, the units have short revamping period, low cost, fast outputing, good economic benefits and should be listed as the emphasis of debottlenecking in capacity expansion of the catalytic reformers. Now it is also a shortcut for gasoline upgrading and updating. Ideas for revamping send-regenerative catalytic reformers were proposed, and practical revamping examples were given.

我国 60~ 70年代投产的半再生重整装置,规模大多为 0.10~ 0.15Mt/a,配有以二乙二醇醚为溶剂的芳烃 抽提部分。但是,这些装置规模小、能耗高、液体产品收率低。这些装置的改造周期短、投资少、产出快、效益好,应 列为重整装置消除“瓶颈”、扩能改造的重点,是目前汽油产品质量升级换代的一条捷径。因此,对半再生重整装置 的改造提出了一些思路,并给出了改造实例。
