<P>PROBLEM TO BE SOLVED: To solve the problem that on eliminating residual metal particles contained in Fisher Tropsch synthetic slurry by a magnetic separation, there is a possibility that the residual metal particles show a weak magnetism in its oxidized state. <P>SOLUTION: This method for eliminating the magnetic particles comprises installing a hydrogenation treatment process separately as a pre-treatment of the magnetic separation process to make the metal particles in a reduced state, and thus the magnetic separation efficiency in the magnetic separation process is improved. <P>COPYRIGHT: (C)2010,JPO&INPIT |
