Choice removal manner of the FT catalytic converter where the inside of the FT synthetic oil deactivates

摘要

P To selectively separate residual catalyst particles in Fisher Tropsch synthesis, having a low magnetism and low activity, and discharge them to the outside of a system and also obtain FT synthetic crude oil reduced with the residues. PSOLUTION: Since the catalyst reduced in activity has a reduced magnetism, the residual catalysts are separated by 2 stages, in the first high gradient magnetic separation process, the particles having higher magnetism are separated and recycled, and in the separation by a second filter and the captured particles having a low magnetism are discharged from the system and thus the catalysts reduced in its activity are selectively eliminated to improve reaction efficiency and also the clean FT synthetic crude oil reduced in the residues can be obtained.
