METHOD FOR RECYCLING FT CATALYST IN FT SYNTHETIC OIL

摘要

PROBLEM TO BE SOLVED: To selectively separate highly reactive catalyst particles from Fisher Tropsch synthesis slurry and recycle them to a reactor.;SOLUTION: 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, particles having a lower magnetism is separated and discharged to the outside of the system. Thus, it becomes possible to selectively recycle the highly active residual catalyst.;COPYRIGHT: (C)2010,JPO&INPIT
