CORE-SHELL COBALT CATALYSTS FOR FISCHER-TROPSCH SYNTHESIS REACTION AND PREPARING METHOD THEREOF

摘要

The present invention relates to a core-shell cobalt catalyst used for a Fischer-Tropsch synthesis reaction and a method for preparing the same. More particularly, it relates to a cobalt catalyst, which has a core-shell structure including a cobalt-supported and sintered alumina particle as a core and a zeolite powder coated on the surface of the alumina particle to a thickness of 50 μm or greater through mechanical alloying as a shell and is used to prepare hydrocarbons with high octane numbers through a Fischer-Tropsch synthesis reaction, and a method for preparing the same.

1. A core-shell cobalt catalyst for a Fischer-Tropsch synthesis reaction, which comprises a spherical, cobalt-supported and sintered alumina particle having a diameter of 1-5 mm as a core and a zeolite powder having a SiO2/Al2O3 molar ratio of 5-40 coated on the surface of the core to a thickness of 50-300 μm through a mechanical alloying process as a shell.
