The manner which recycles the FT catalytic converter in the FT synthetic oil

摘要

P To selectively separate highly reactive catalyst particles from Fisher Tropsch synthesis slurry and recycle them to a reactor. PSOLUTION: By magnetically separating the catalyst contained in the slurry by 2 stages, higher magnetic particles are separated by a first high gradient magnetic separation process and recycled to the reactor, since they are highly active, and in the second magnetic separation process and particles having a lower magnetism is separated and discharged to the outside of the system. Thus and it becomes possible to selectively recycle the highly active residual catalyst. PCOPYRIGHT: (C)2010 and JPO& INPIT
