Introduction
A new continuous reforming process called counter-current continuous catalytic reforming process has been developed by SINOPEC. The regenerated catalyst firstly enters the last reactor. Then it’s conveyed to the first reactor while the feed still flows from the first reactor to the last one. After reaction, the spent catalyst is lifted to the regenerator to be regenerated. Catalyst has the highest activity in the last reactor and the lowest activity in the first reactor. In this way, the high activity catalyst is used to promote the difficult reactions and low activity catalyst is used in the easy reactions, which makes the catalyst activity matches with the reaction difficulty. So the counter-current catalytic reforming process has overcome the limitation of the traditional co-current process.
Counter-current continuous catalytic reforming process not only improves the reaction conditions, but also creates a new catalyst circulation method with simplified operation. Compared with the traditional process, this process has three remarkable features. Firstly, the flow direction of catalyst is from the last reactor to the first reactor. Secondly, catalyst transportation from low pressure to high pressure is achieved by means of catalyst sealing legs instead of the complicated lock-hopper and relevant control system. Thirdly, there is only one catalyst dust elutriation system.
